Subject: [PATCH mlx5-next v3 01/13] net/mlx5: Add ifc bits to support optional counters
Date: Wed,  6 Oct 2021 12:52:04 +0300	[thread overview]
Message-ID: <7afaf0a646c014ad1ba777377dd5d44f7d3ce337.1633513239.git.leonro@nvidia.com> (raw)
In-Reply-To: <cover.1633513239.git.leonro@nvidia.com>

From: Aharon Landau <aharonl@nvidia.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.
