Revert "net: maintain namespace isolation between vlan and real device"
This reverts commit 8a83a00b0735190384a348156837918271034144. It causes regressions for S390 devices, because it does an unconditional DST drop on SKBs for vlans and the QETH device needs the neighbour entry hung off the DST for certain things on transmit. Arnd can't remember exactly why he even needed this change. Conflicts: drivers/net/macvlan.c net/8021q/vlan_dev.c net/core/dev.c Signed-off-by: David S. Miller <davem@davemloft.net>
