Subject: [dpdk-dev] [RFC v3 7/8] net/mlx5: add GENEVE TLV option flow translation
Date: Wed, 16 Dec 2020 15:02:14 +0200 [thread overview]
Message-ID: <1608123735-3662-8-git-send-email-shirik@nvidia.com> (raw)
In-Reply-To: <1608123735-3662-1-git-send-email-shirik@nvidia.com>
The GENEVE TLV option matching flows must be created
using a translation function.
This function checks whether we already created a Devx
object for the matching and either creates the objects
or updates the reference counter.
