ethdev: add packet integrity check flow rules

Currently, DPDK application can offload the checksum check,
and report it in the mbuf.

However, as more and more applications are offloading some or all
logic and action to the HW, there is a need to check the packet
integrity so the right decision can be taken.

The application logic can be positive meaning if the packet is
valid jump / do  actions, or negative if packet is not valid
jump to SW / do actions (like drop) and add default flow
(match all in low priority) that will direct the miss packet
to the miss path.

Since currently rte_flow works in positive way the assumption is
that the positive way will be the common way in this case also.

When thinking what is the best API to implement such feature,
we need to consider the following (in no specific order):
1. API breakage.
2. Simplicity.
3. Performance.
4. HW capabilities.
5. rte_flow limitation.
6. Flexibility.

First option: Add integrity flags to each of the items.
For example add checksum_ok to IPv4 item.

Pros:
1. No new rte_flow item.
2. Simple in the way that on each item the app can see
what checks are available.

Cons:
1. API breakage.
2. Increase number of flows, since app can't add global rule and must
   have dedicated flow for each of the flow combinations, for example
   matching on ICMP traffic or UDP/TCP  traffic with IPv4 / IPv6 will
   result in 5 flows.

Second option: dedicated item

Pros:
1. No API breakage, and there will be no for some time due to having
   extra space. (by using bits)
2. Just one flow to support the ICMP or UDP/TCP traffic with IPv4 /
   IPv6.
3. Simplicity application can just look at one place to see all possible
   checks.
4. Allow future support for more tests.

Cons:
1. New item, that holds number of fields from different items.

For starter the following bits are suggested:
1. packet_ok - means that all HW checks depending on packet layer have
   passed. This may mean that in some HW such flow should be split to
   number of flows or fail.
2. l2_ok - all check for layer 2 have passed.
3. l3_ok - all check for layer 3 have passed. If packet doesn't have
   L3 layer this check should fail.
4. l4_ok - all check for layer 4 have passed. If packet doesn't
   have L4 layer this check should fail.
5. l2_crc_ok - the layer 2 CRC is O.K.
6. ipv4_csum_ok - IPv4 checksum is O.K. It is possible that the
   IPv4 checksum will be O.K. but the l3_ok will be 0. It is not
   possible that checksum will be 0 and the l3_ok will be 1.
7. l4_csum_ok - layer 4 checksum is O.K.
8. l3_len_OK - check that the reported layer 3 length is smaller than the
   frame length.

Example of usage:
1. Check packets from all possible layers for integrity.
   flow create integrity spec packet_ok = 1 mask packet_ok = 1 .....

2. Check only packet with layer 4 (UDP / TCP)
   flow create integrity spec l3_ok = 1, l4_ok = 1 mask l3_ok = 1
   l4_ok = 1

ethdev: introduce indirect flow action

Right now, rte_flow_shared_action_* APIs are used for some shared
actions, like RSS, count. The shared action should be created before
using it inside a flow. These shared actions sometimes are not
really shared but just some indirect actions decoupled from a flow.

The new functions rte_flow_action_handle_* are added to replace
the current shared functions rte_flow_shared_action_*.

There are two types of flow actions:
1. the direct (normal) actions that could be created and stored
   within a flow rule. Such action is tied to its flow rule and
   cannot be reused.
2. the indirect action, in the past, named shared_action. It is
   created from a direct actioni, like count or rss, and then used
   in the flow rules with an object handle. The PMD will take care
   of the retrieve from indirect action to the direct action
   when it is referenced.

The indirect action is accessed (update / query) w/o any flow rule,
just via the action object handle. For example, when querying or
resetting a counter, it could be done out of any flow using this
counter, but only the handle of the counter action object is
required.
The indirect action object could be shared by different flows or
used by a single flow, depending on the direct action type and
the real-life requirements.
The handle of an indirect action object is opaque and defined in
each driver and possibly different per direct action type.

The old name "shared" is improper in a sense and should be replaced.

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*", the testpmd application code and command
line interfaces also need to be updated to do the adaption.
The testpmd application user guide is also updated. All the "shared
action" related parts are replaced with "indirect action" to have a
correct explanation.

The parameter of "update" interface is also changed. A general
pointer will replace the rte_flow_action struct pointer due to the
facts:
1. Some action may not support fields updating. In the example of a
   counter, the only "update" supported should be the reset. So
   passing a rte_flow_action struct pointer is meaningless and
   there is even no such corresponding action struct. What's more,
   if more than one operations should be supported, for some other
   action, such pointer parameter may not meet the need.
2. Some action may need conditional or partial update, the current
   parameter will not provide the ability to indicate which part(s)
   to update.
   For different types of indirect action objects, the pointer could
   either be the same of rte_flow_action* struct - in order not to
   break the current driver implementation, or some wrapper
   structures with bits as masks to indicate which part to be
   updated, depending on real needs of the corresponding direct
   action. For different direct actions, the structures of indirect
   action objects updating will be different.

All the underlayer PMD callbacks will be moved to these new APIs.

The RTE_FLOW_ACTION_TYPE_SHARED is kept for now in order not to
break the ABI. All the implementations are changed by using
RTE_FLOW_ACTION_TYPE_INDIRECT.

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*" and the "update" interface's 3rd input
parameter is changed to generic pointer, the mlx5 PMD that uses these
APIs needs to do the adaption to the new APIs as well.

ethdev: add queue state in queried queue information

Note: After add queue_state field, the 'struct rte_eth_rxq_info' size

lib: simplify main build file

Two simplifications can be made to the build file which reduce indentation
levels and make it easier to read:

1. When meson build support was first added, the compat library existed in
DPDK as a single header file. Since that header has been merged into EAL,
we no longer need to support header-only libraries, so can shorten the
code.

2. From meson 0.49 onwards we have the "continue" keyword available to
break out of one loop iteration and begin the next. This allows us to
remove blocks in the build configuration file which were conditional on the
"build" variable being true. Instead we can use "continue" to abort
processing at the point where the "build" value becomes false.

Since this patch changes the indentation level of large parts of the
meson.build file, we use the opportunity to adjust the whitespace used to
the meson-standard 4-spec indentation level.

kni: fix kernel deadlock with bifurcated device

KNI runs userspace callback with rtnl lock held, this is not working
fine with some devices that needs to interact with kernel interface in
the callback, like Mellanox devices.

The solution is releasing the rtnl lock before calling the userspace
callback. But it requires two consideration:

1. The rtnl lock needs to released before 'kni->sync_lock', otherwise it
   causes deadlock with multiple KNI devices, please check below the A.
   for the details of the deadlock condition.

2. When rtnl lock is released for interface down event, it cause a
   regression and deadlock, so can't release the rtnl lock for interface
   down event, please check below B. for the details.

As a solution, interface down event is handled asynchronously and for
all other events rtnl lock is released before processing the callback.

A. KNI sync lock is being locked while rtnl is held.
If two threads are calling kni_net_process_request() ,
then the first one will take the sync lock, release rtnl lock then sleep.
The second thread will try to lock sync lock while holding rtnl.
The first thread will wake, and try to lock rtnl, resulting in a
deadlock.  The remedy is to release rtnl before locking the KNI sync
lock.
Since in between nothing is accessing Linux network-wise, no rtnl
locking is needed.

B. There is a race condition in __dev_close_many() processing the
close_list while the application terminates.
It looks like if two KNI interfaces are terminating,
and one releases the rtnl lock, the other takes it,
updating the close_list in an unstable state,
causing the close_list to become a circular linked list,
hence list_for_each_entry() will endlessly loop inside
__dev_close_many() .

To summarize:
request != interface down : unlock rtnl, send request to user-space,
wait for response, send the response error code to caller in user-space.

request == interface down: send request to user-space, return immediately
with error code of 0 (success) to user-space.

pipeline: auto-detect endianness of action arguments

Each table entry is made up of match fields and action data, with the
latter made up of the action ID and the action arguments. The approach
of having the user specify explicitly the endianness of the action
arguments is difficult to be picked up by P4 compilers, as the P4
compiler is generally unaware about this aspect.

This commit introduces the auto-detection of the endianness of the
action arguments by examining the endianness of the their destination:
network byte order (NBO) when they get copied to headers and host byte
order (HBO) when they get copied to packet meta-data or mailboxes.

The endianness specification of each action argument as part of the
rule specification, e.g. H(...) and N(...) is removed from the rule
file and auto-detected based on their destination. The DMA instruction
scope is made internal, so mov instructions need to be used. The
pattern of transferring complete headers from table entry action args
to headers is detected, and the associated set of mov instructions
plus header validate is internally detected and replaced with the
internal-only DMA instruction to preserve performance.

eventdev: introduce crypto adapter enqueue API

In case an event from a previous stage is required to be forwarded
to a crypto adapter and PMD supports internal event port in crypto
adapter, exposed via capability
RTE_EVENT_CRYPTO_ADAPTER_CAP_INTERNAL_PORT_OP_FWD, we do not have
a way to check in the API rte_event_enqueue_burst(), whether it is
for crypto adapter or for eth tx adapter.

Hence we need a new API similar to rte_event_eth_tx_adapter_enqueue(),
which can send to a crypto adapter.

Note that RTE_EVENT_TYPE_* cannot be used to make that decision,
as it is meant for event source and not event destination.
And event port designated for crypto adapter is designed to be used
for OP_NEW mode.

Hence, in order to support an event PMD which has an internal event port
in crypto adapter (RTE_EVENT_CRYPTO_ADAPTER_OP_FORWARD mode), exposed
via capability RTE_EVENT_CRYPTO_ADAPTER_CAP_INTERNAL_PORT_OP_FWD,
application should use rte_event_crypto_adapter_enqueue() API to enqueue
events.

When internal port is not available(RTE_EVENT_CRYPTO_ADAPTER_OP_NEW mode),
application can use API rte_event_enqueue_burst() as it was doing earlier,
i.e. retrieve event port used by crypto adapter and bind its event queues
to that port and enqueue events using the API rte_event_enqueue_burst().

net/i40e: fix lack of MAC type when set MAC address

Currently, there is no way for a VF driver to specify that it wants to
change its device/primary unicast MAC address. This makes it
difficult/impossible for the PF driver to track the VF's device/primary
unicast MAC address, which is used for VM/VF reboot and displaying on
the host. Fix this by using 2 bits of a pad byte in the
virtchnl_ether_addr structure so the VF can specify what type of MAC
it's adding/deleting.

Below are the values that should be used by all VF drivers going
forward.

VIRTCHNL_ETHER_ADDR_LEGACY(0):
- The type should only ever be 0 for legacy AVF drivers (i.e.
  drivers that don't support the new type bits). The PF drivers
  will track VF's device/primary unicast MAC using with best
  effort.

VIRTCHNL_ETHER_ADDR_PRIMARY(1):
- This type should only be used when the VF is changing their
  device/primary unicast MAC. It should be used for both delete
  and add cases related to the device/primary unicast MAC.

VIRTCHNL_ETHER_ADDR_EXTRA(2):
- This type should be used when the VF is adding and/or deleting
  MAC addresses that are not the device/primary unicast MAC. For
  example, extra unicast addresses and multicast addresses
  assuming the PF supports "extra" addresses at all.

If a PF is parsing the type field of the virtchnl_ether_addr, then it
should use the VIRTCHNL_ETHER_ADDR_TYPE_MASK to mask the first two bits
of the type field since 0, 1, and 2 are the only valid values.

For i40evf PMD, when set default MAC address, use type
VIRTCHNL_ETHER_ADDR_PRIMARY as this case is changing device/primary
unicast MAC. For other cases, such as adding or deleting extra unicast
addresses and multicast addresses, use type VIRTCHNL_ETHER_ADDR_EXTRA.
