net/enic: ignore VLAN inner type when it is zero

When a VLAN pattern is present, the flow handler always copies its
inner_type to the match buffer regardless of its value (i.e. HW
matches inner_type against packet's inner ethertype). When inner_type
spec and mask are both 0, adding it to the match buffer is usually
harmless but breaks the following pattern used in some applications
like OVS-DPDK.

flow create 0 ingress ... pattern eth ... type is 0x0800 /
vlan tci spec 0x2 tci mask 0xefff / ipv4 / end actions count /
of_pop_vlan / ...

The VLAN pattern's inner_type is 0. And the outer eth pattern's type
actually specifies the inner ethertype. The outer ethertype (0x0800)
is first copied to the match buffer. Then, the driver copies
inner_type (0) to the match buffer, which overwrites the existing
0x0800 with 0 and breaks the app usage above.

Simply ignore inner_type when it is 0, which is the correct
behavior. As a byproduct, the driver can support the usage like the
above.

net/enic: extend flow handler to support VF representors

VF representor ports can create flows on VFs through the PF flowman
(Flow Manager) instance in the firmware. These flows match packets
egressing from VFs and apply flowman actions.

1. Make flow handler aware of VF representors
When a representor port invokes flow APIs, use the PF port's flowman
instance to perform flowman devcmd. If the port ID refers to a
representor, use VF handle instead of PF handle.

2. Serialize flow API calls
Multiple application thread may invoke flow APIs through PF and VF
representor ports simultaneously. This leads to races, as ports all
share the same PF flowman instance. Use a lock to serialize API
calls. Lock is used only when representors exist.

3. Add functions to create flows for implicit representor paths
There is an implicit path between VF and its representor. The
functions below create flow rules to implement that path.
- enic_fm_add_rep2vf_flow()
- enic_fm_add_vf2rep_flow()

The flows created for representor paths are marked as internal. These
are not visible to application, and the flush API does not destroy
them. They are automatically deleted when the representor port stops
(enic_fm_destroy).

1. Enable the standard devarg 'representor'
When the devarg is specified, create VF representor ports.

2. Initialize flowman early during PF probe
Representors require the flowman API from the firmware. Initialize it
before creating VF representors, so probe can detect the flowman
support and fail if not available.

3. Add enic_fm_allocate_switch_domain() to allocate switch domain ID
PFs and VFs on the same VIC adapter can forward packets to each other,
so the switch domain is the physical adapter.

4. Create a vnic_dev lock to serialize concurrent devcmd calls
PF and VF representor ports may invoke devcmd (e.g. dump stats)
simultaneously. As they all share a single PF devcmd instance in the

1. Add vnic_vf_rep_register()
A VF representor creates its own vnic_dev instance via this function
and saves VF ID. When performing devcmd, vnic_dev uses the saved VF ID
to proxy devcmd through the PF vnic_dev instance.

2. Add vnic_register_lock()
As PF and VF representors appear as independent ports to the
application, its threads may invoke APIs on them simultaneously,
leading to race conditions on the PF vnic_dev. For example, thread A
can query stats on PF port, while thread B queries stats on a VF
representor.

The PF port invokes this function to provide a lock to vnic_dev. This
lock is used to serialize devcmd calls from PF and VF representors.

3. Add utility functions to assist VF representor settings
vnic_dev_mtu() and vnic_dev_uif() retrieve vnic MTU and UIF number

network engine. The related core dump information as follows:

9  0x0000ffffa6ed1600 in thread_start

The root cause is that hns3 PMD driver invokes the rte_pktmbuf_free_seg
API function to release the same rte_mbuf multiple times. The rte_mbuf
pointer is not set to NULL in the internal function
hns3_rx_queue_release_mbufs which is invoked during queue setup, stop
and close. As a result the rte_mbuf in Rx queues will be repeatedly
released when the user application setup queues or stop/start the dev
for multiple times.
Probably for performance reasons, DPDK mempool lib does not check for
the repeated rte_mbuf releases. The Address of released rte_mbuf are
directly stored into the per lcore cache of the mempool. This makes the
rte_mbufs obtained from mempool by calling rte_mempool_get_bulk API
function repetitively.  ultimately, it causes to access to a NULL
pointer in PMD driver.

This patch fixes this problem by setting released mbuf pointer to NULL
in the internal function named hns3_rx_queue_release_mbuf. And the other
internal function named hns3_reassemble_tx_pkts is optimized to avoid a
similar problem.

ethdev: format link status text

There is new link_speed value introduced. It's INT_MAX value which
means that speed is unknown. To simplify processing of the value
in application, new function is added which convert link_speed to
string. Also dpdk examples have many duplicated code which format
entire link status structure to text.

This commit adds two functions:
  * rte_eth_link_speed_to_str - format link_speed to string
  * rte_eth_link_to_str - convert link status structure to string

net/af_xdp: fix umem size

The kernel expects the start address of the UMEM to be page size
aligned.
Since the mempool is not guaranteed to have such alignment, we have been
aligning the address to the start of the page the mempool is on. However
when passing the 'size' of the UMEM during it's creation we did not take
this into account.

When HW is faster than SW, it may be that all the FW resources are busy

net/bnxt: refactor VFR port clean up

When parent VF or PF ports are cleaned up, the child VF representor
ports also need to be cleaned up. If not cleaned up, then deleting
the parent VF shall result in not cleaning up the hardware rules and
updating the firmware of VFR removal. The issue can occur even when
application is exited without deleting VFR ports.

net/bnxt: modify default flow rule creation

Change default flow rule to use 8-byte encap.
The VFR conduit uses VLAN encap to send packets. So the encap record
is changed from 16B to 8B. That frees up 8B of encap records.
