Subject: [dpdk-dev] [PATCH 1/4] net/mlx5: remove hairpin queue peer port checking
Date: Thu,  8 Oct 2020 22:16:57 +0800
Message-ID: <1602166620-46303-2-git-send-email-bingz@nvidia.com> (raw)
In-Reply-To: <1602166620-46303-1-git-send-email-bingz@nvidia.com>

In the current implementation of single port mode hairpin, the peer
queue should belong to the same port of the current port. When two
ports hairpin mode is introduced, the checking should be removed to
make the hairpin queue setup execute successfully.
