[PATCH rdma-next 0/7] Mellanox ConnectX-4/Connect-IB sniffer support

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

This patch set adds sniffer support to mlx5 flow steering.
A sniffer rule could be created via ib_create_flow verb with
IB_FLOW_ATTR_SNIFFER type. When the user adds a sniffer rule,
its destination QP expects to receive all incoming and
outgoing packets from the port. Only raw packet QPs are
supported as destinations.

In ConnectX-4 based adapters, each incoming packet is duplicated and
sent to the sniffer RX flow table in addition to the NIC RX root flow
table. Each out going packet is duplicated and sent to the sniffer TX
flow table in addition to the wire.

In order to sniff all the traffic, we add a single "*" rule both
to the RX and TX sniffer flow tables. "*" rule is used to receive
all the traffic, this rule don't contain any criteria.

Available in the "topic/sniffer-verb" topic branch of this git repo:
