From f00f49243901f435d5bc8fbe8a6ad9ecf74a6247 Mon Sep 17 00:00:00 2001 From: Marcin Szycik Date: Wed, 25 Oct 2023 16:47:24 +0200 Subject: [PATCH] ice: Fix VF-VF direction matching in drop rule in switchdev [ Upstream commit 68c51db3a16d258e730dd1c04a1de2f7ab038ddf ] When adding a drop rule on a VF, rule direction is not being set, which results in it always being set to ingress (ICE_ESWITCH_FLTR_INGRESS equals 0). Because of this, drop rules added on port representors don't match any packets. To fix it, set rule direction in drop action to egress when netdev is a port representor, otherwise set it to ingress.
