From: Michal Swiatkowski Date: Fri, 1 Mar 2024 11:54:10 +0000 (+0100) Subject: ice: control default Tx rule in lag X-Git-Tag: v6.10-rc1~153^2~421^2~4 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9cba6e1767bf8286563ae8907d6e595c365d3e92;p=thirdparty%2Fkernel%2Flinux.git ice: control default Tx rule in lag Tx rule in switchdev was changed to use PF instead of additional control plane VSI. Because of that during lag we should control it. Control means to add and remove the default Tx rule during lag active/inactive switching. It can be done the same way as default Rx rule.
