From: Roi Dayan Date: Tue, 1 Feb 2022 13:27:48 +0000 (+0200) Subject: net/mlx5e: Avoid implicit modify hdr for decap drop rule X-Git-Tag: v5.16.6~17 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e23a2f4e43a4a18de4137a446705281a8969b375;p=thirdparty%2Fkernel%2Fstable.git net/mlx5e: Avoid implicit modify hdr for decap drop rule commit 5b209d1a22afabfb7d644abb10510c5713a3e569 upstream. Currently the driver adds implicit modify hdr action for decap rules on tunnel devices if the port is an ovs port. This is also done if the action is drop and makes the modify hdr redundant and also the FW doesn't support it and will generate a syndrome. kernel: mlx5_core 0000:08:00.0: mlx5_cmd_check:777:(pid 102063): SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x8708c3) Fix it by adding the implicit modify hdr only for fwd actions.
