Disambiguate based on netdev_uses_dsa() +whether this is a VLAN or DSA hwaccel tag, and only call +__vlan_hwaccel_put_tag() if we're certain it's a VLAN tag. + +Arınç confirms that the treatment works, so this validates the +assumption. + +Link: https://lore.kernel.org/netdev/704f3a72-fc9e-714a-db54-272e17612637@arinc9.com/ +Fixes: 2d7605a72906 ("net: ethernet: mtk_eth_soc: enable hardware DSA untagging") +Reported-by: Arınç ÜNAL +Tested-by: Arınç ÜNAL +Signed-off-by: Vladimir Oltean +Reviewed-by: Felix Fietkau +Signed-off-by: David S.
