[v2,00/41] add MLX5 FreeBSD support

This patch series introduces FreeBSD OS support for MLX5 PMD

Currently there is an ongoing review of FreeBSD OFED drivers and
RDMA-core libraries. Their status can be tracked at
https://reviews.freebsd.org/p/vag.singh_oneconvergence.com

Only MLX5 SRIOV interface is supported along with the following features:

  - Hypervisors: KVM, ESXi and Azure/HyperV
  - Multiple Tx and Rx queues
  - Support for scattered Tx and Rx frames
  - RSS
  - VLAN filtering, stripping and insertion
  - RX CRC stripping configuration
  - Promiscuous and Multicast mode
  - Statistics query including Basic, Extended, and per queue.
  - Configurable MTU and MAC
  - Jumbo frame support
  - Trust mode support
  - Vxlan
  - QoS
  - Flow steering

Tested on :
MT27710 Family [ConnectX-4 Lx]
MT27710 Family [ConnectX-4 Lx Virtual Function] (Azure)
MT27700 Family [ConnectX-4]
MT27800 Family [ConnectX-5]
MT2894 Family  [ConnectX-6 Lx]
MT28908 Family [ConnectX-6]
MT2892 Family  [ConnectX-6 Dx]

What is the status of the dependencies on FreeBSD side?
It seems to be blocked.

It seems the review of the DPDK series did not start.
We should probably have a progress on the FreeBSD side first.
