bridge: Use the correct bit length for bitmap functions in the VLAN code
The VLAN code needs to know the length of the per-port VLAN bitmap to perform its most basic operations (retrieving VLAN informations, removing VLANs, forwarding database manipulation, etc). Unfortunately, in the current implementation we are using a macro that indicates the bitmap size in longs in places where the size in bits is expected, which in some cases can cause what appear to be random failures. Use the correct macro. Signed-off-by: Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp> Signed-off-by: David S. Miller <davem@davemloft.net>
