Log:
  in6_if2idlen: treat bridge(4) interfaces like other Ethernet interfaces
  
  bridge(4) interfaces have an if_type of IFT_BRIDGE, rather than
  IFT_ETHER, even though they only support Ethernet-style links.  This
  caused in6_if2idlen to emit an "unknown link type (209)" warning to
  the console every time it was called.  Add IFT_BRIDGE to the case
  statement in the appropriate place, indicating that it uses the same
  IPv6 address format as other Ethernet-like interfaces.
