[VLAN]: Don't copy ALLMULTI/PROMISC flags from underlying device
Changing these flags requires to use dev_set_allmulti/dev_set_promiscuity or dev_change_flags. Setting it directly causes two unwanted effects: - the next dev_change_flags call will notice a difference between dev->gflags and the actual flags, enable promisc/allmulti mode and incorrectly update dev->gflags - this keeps the underlying device in promisc/allmulti mode until the VLAN device is deleted Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
