Subject: [dpdk-dev] [PATCH 1/5] net/mlx5: remove handling of ICMP fragmented packets
Date: Tue, 13 Oct 2020 17:16:11 +0300
Message-ID: <08688f17326e30e6981d35e1d0677dd7d66e2eeb.1602598055.git.dekelp@nvidia.com> (raw)
In-Reply-To: <cover.1602598055.git.dekelp@nvidia.com>

Commit [1] forced setting of match on 'frag' bit mask 1 and value 0.
Previous patch in this series added support of match on fragmented and
non-fragmented packets on L3 items, so this setting is now redundant.

This patch removes the changes done in [1].

[1] commit 85407db9f60d ("net/mlx5: fix matching for ICMP fragments")
