From: Paul Blakey Date: Mon, 16 Mar 2020 12:55:11 +0000 (+0200) Subject: net/mlx5: E-Switch, Skip restore modify header between prios of same chain X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e0cb8afdbba909085514f02a3df2d17e7eac1ae6;p=linux.git net/mlx5: E-Switch, Skip restore modify header between prios of same chain Restore modify header writes the chain mapping on the packet. This modify header and action is added on all prios connections, and gets overwritten with the same value consecutively in prios of the same chain. Use the chain's modify header only for the last prio of a given tc chain.
