Subject: [PATCH rdma-next v4 01/13] net/mlx5: Add ifc bits to support optional counters

From: Aharon Landau <aharonl@...dia.com>

Adding bth_opcode field and the relevant bits. This field will be used
to capture and count congestion notification packets (CNP).

Adding source_vhca_port support bit.
This field will be used to check the capability to use the
source_vhca_port as a match criteria in cases of dual port.
