Subject: [dpdk-dev] [RFC v3 3/8] common/mlx5: check GENEVE TLV support in HCA attributes
Date: Wed, 16 Dec 2020 15:02:10 +0200
Message-ID: <1608123735-3662-4-git-send-email-shirik@nvidia.com> (raw)
In-Reply-To: <1608123735-3662-1-git-send-email-shirik@nvidia.com>

This is preparation step to support match on GENEVE TLV option.

In this Patch we add the HCA attributes that will allow
supporting GENEVE TLV option matching.
