From: Maor Gottlieb Date: Thu, 18 Mar 2021 13:51:23 +0000 (+0200) Subject: RDMA/mlx5: Fix drop packet rule in egress table X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c73700806d4e430d182c2be069d230076818a99a;p=linux.git RDMA/mlx5: Fix drop packet rule in egress table Initial drop action support missed that drop action can be added to egress flow tables as well. Add the missing support. This requires making sure that dest_type isn't set to PORT which in turn exposes a possibility of passing dst while indicating number of dsts as zero. Explicitly check for number of dsts and pass the appropriate pointer.
