ethdev: clarify flow API pattern items and actions
Although pattern items and actions examples end with "and so on", these
lists include all existing definitions and as a result are updated almost
every time new types are added. This is cumbersome and pointless.
This patch also synchronizes Doxygen and external API documentation wording
with a slight clarification regarding meta pattern items.
No fundamental API change.

ethdev: remove experimental flag of ports enumeration
The basic operations for ports enumeration should not be
considered as experimental in DPDK 18.05.
The iterator RTE_ETH_FOREACH_DEV was introduced in DPDK 17.05.
It uses the function the rte_eth_find_next_owned_by() to get
only ownerless ports. Its API can be considered stable.
So the flag experimental is removed from rte_eth_find_next_owned_by().
The flag experimental is removed from rte_eth_dev_count_avail()
which is the new name of the old function rte_eth_dev_count().
The flag experimental is set to rte_eth_dev_count_total()
in the .c file for consistency with the declaration in the .h file.
A lot of internal applications are fixed to not allow experimental API.

net/bonding: support flow API
Ethernet devices which are grouped by bonding PMD, aka slaves, are
sharing the same queues and RSS configurations and their Rx burst
functions must be managed by the bonding PMD according to the bonding
architecture.
So, it makes sense to configure the same flow rules for all the bond
slaves to allow consistency in packet flow management.
Add rte flow support to the bonding PMD to manage all flow
configuration to the bonded slaves.
Add command to change specific queue's ring size configure,
the new value will only take effect after command that restart
the device(port stop <port_id>/port start <port_id>) or command
that setup the queue(port <port_id> rxq <qid> setup) at runtime.
Each queue has independent configure information in rte_port.
Base on this, we are able to add new commands to configure
different queues with different value.
It's not possible to setup a queue when the port is started
because of a check in ethdev layer. New capability flags are
added in order to relax this check for devices which support
queue setup in runtime. The functions rte_eth_[rx|tx]_queue_setup
will raise an error only if the port is started and runtime setup
of queue is not supported.

PMDs have the responsibility of releasing mbufs sent through xmit burst
function. NFP PMD attaches those sent mbufs to the TX ring structure,
and it is at the next time a specific ring descriptor is going to be
used when the previous linked mbuf, already transmitted at that point,
is released. Those mbufs belonging to a chained mbuf got its own link
to a ring descriptor, and they are released independently of the mbuf
head of that chain.
The problem is how those mbufs are released when the PMD is stopped or
closed. Instead of releasing those mbufs as the xmit functions does,
this is independently of being in a mbuf chain, the code calls
rte_pktmbuf_free which will release not just the mbuf head in that
chain but all the chained mbufs. The loop will try to release those
mbufs which have already been released again when chained mbufs exist.
This patch fixes the problem using rte_pktmbuf_free_seg instead.
There is an option to run a non-netvsc device as a netvsc device only
when the "force" parameter is set to 1 in the EAL command line.
Consequently, more than one device may be found to be matching the
"mac" parameter specifying the device.
Prefer netvsc devices to be scanned before any non-netvsc device, even
when the "force" parameter is set.
net/vdev_netvsc: remove specified devices IP check
If the netvsc driver starts in blacklist mode, it does not
automatically probe IP associated netvsc devices. Therefore, the only
way to probe them is to specify them by the EAL command line, using the
"force" parameter to skip the IP check in the driver.
>From now on, the user does not need to add the "force" parameter if he
specifies an IP associated netvsc device by the EAL command line, and the
responsibility of the IP check is now in the user's hands.
However, in the absence of any specification, the driver still skips IP
associated netvsc devices.
Prior to this commit the vdev_netvsc PMD was creating tap and failsafe
devices with long names, such as "net_tap_net_vdev_netvsc0" or
"net_failsafe_net_vdev_netvsc0".
This commits creates tap and failsafe devices with short names such as
"net_tap_netvsc0" or "net_failsafe_netvsc0".

app/testpmd: fix missing boolean values in flow command
Original implementation lacks the on/off toggle.
This patch shows up as a fix because it has been a popular request ever
since the first DPDK release with the original implementation but was never
addressed.
Except for a list of queues, RSS configuration (hash key and fields) cannot
be specified from the flow command line and testpmd does not provide safe
defaults either.
In order to validate their implementation with testpmd, PMDs had to
interpret its NULL RSS configuration parameters somehow, however this has
never been valid to begin with.
This patch makes testpmd always provide default values.
The list of RSS types to use is exclusively taken from the global "rss_hf"
variable, itself configured through the "port config all rss" command or
--rss-ip/--rss-udp command-line options.
app/testpmd: fix lack of flow action configuration
Configuration structure is not optional with flow rule actions that expect
one; this pointer is not supposed to be NULL and PMDs should not have to
verify it.
Like pattern item spec/last/mask fields, it is currently set when at least
one configuration parameter is provided on the command line. This patch
sets it as soon as an action is created instead.
When an unsupported hash type is part of a RSS configuration structure, it
is silently ignored instead of triggering an error. This may lead
applications to assume that such types are accepted, while they are in fact
not part of the resulting flow rules.

Since we are storing the mem_zone address for each ring created,
we are freeing the same address multiple times.
For example the memory zone created for Rx is being freed during
Rx ring cleanup, AGG ring cleanup and CQ cleanup.
Avoid this by storing the memory zone address in RXQ instead and
free it as a part of queue_release dev_op.
In the same way do the same for TX queues as well.
The fw_l2_filter_id for a ntuple filter is needed only for the lifetime
of the ntuple filter. Once the filter is free, reset the field.
The associated l2_filter will be freed as a part of its own cleanup.

the COS queue that a Tx ring needs to use. This patch adds code

net/enic: enable overlay offload for VXLAN and GENEVE
Recent NIC models support overlay offload. The overlay offload
feature enables the following on the NIC.
- Rx/Tx checksum offloads for both inner and outer packets.
- Rx inner packet type classification.
- TSO.
- Inner RSS.
TX descriptors do not require any changes, except the header length
for TSO. The NIC parses outer/inner packets and performs offloads on
them as necessary. The header length for tunneled TSO includes both
inner and outer headers.
The NIC actually parses and performs the above for NVGRE as well. DPDK
currently has no offload flags for NVGRE, and the hardware has no
controls to individually enable tunnel types either. So do nothing for
now.
The driver enables overlay offload by default. Add a devargs
'disable-overlay=<0|1>' to allow the app to disable it.
