Pullup rev 1.26 (requested by bad in ticket #900)

Interfaces that do checksum offloading indicate the checksum status of
received packets in csum_flags in the packet header.  Packets that are
forwarded over the bridge need to have csum_flags cleared before being
put on the output queue.  Do so in bridge_enqueue(). PR#27007 PR#21831
