bridge: Prepare for forwarding another bridge group addresses
If a bridge is an 802.1ad bridge, it must forward another bridge group addresses (the Nearest Customer Bridge group addresses). (For details, see IEEE 802.1Q-2011 8.6.3.) As user might not want group_fwd_mask to be modified by enabling 802.1ad, introduce a new mask, group_fwd_mask_required, which indicates addresses the bridge wants to forward. This will be set by enabling 802.1ad. Signed-off-by: Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp> Signed-off-by: David S. Miller <davem@davemloft.net>
