Since vid 0 cannot be used for the PVID, we can use vid 0 to indicate that the PVID is not set, which is slightly more efficient than using the VLAN_TAG_PRESENT. Fix the problem by getting rid of using the VLAN_TAG_PRESENT. Signed-off-by: Toshiaki Makita Reviewed-by: Vlad Yasevich Signed-off-by: David S. Miller --- Reading git-diff-tree failed
