From e4417d6950b06fe6c520e937b337daff093220ff Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Wed, 24 Mar 2021 02:30:33 +0100 Subject: net: 8021q: resolve forwarding path for vlan devices Add .ndo_fill_forward_path for vlan devices. For instance, assuming the following topology: IP forwarding / \ eth0.100 eth0 | eth0 . . . ethX ab:cd:ef:ab:cd:ef For packets going through IP forwarding to eth0.100 whose destination MAC address is ab:cd:ef:ab:cd:ef, dev_fill_forward_path() provides the following path: eth0.100 -> eth0 Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S.
