Miller" <davem@...emloft.net>, Jakub Kicinski <kuba@...nel.org> Cc: netdev@...r.kernel.org, Roi Dayan <roid@...dia.com>, Oz Shlomo <ozsh@...dia.com>, Saeed Mahameed <saeedm@...dia.com> Subject: [net 13/19] net/mlx5e: TC, Reject rules with forward and drop actions From: Roi Dayan <roid@...dia.com> Such rules are redundant but allowed and passed to the driver. The driver does not support offloading such rules so return an error.
