From ab8075d3a4a8cbeb21d39deb170961dfccf2325b Mon Sep 17 00:00:00 2001 From: Will Mortensen Date: Thu, 5 Oct 2023 22:37:06 -0700 Subject: [PATCH] net/mlx5e: Again mutually exclude RX-FCS and RX-port-timestamp [ Upstream commit da6192ca72d5ad913d109d43dc896290ad05d98f ] Commit 1e66220948df8 ("net/mlx5e: Update rx ring hw mtu upon each rx-fcs flag change") seems to have accidentally inverted the logic added in commit 0bc73ad46a76 ("net/mlx5e: Mutually exclude RX-FCS and RX-port-timestamp"). The impact of this is a little unclear since it seems the FCS scattered with RX-FCS is (usually?) correct regardless.
