    Fix PR 48104

    So far bridge cannot receive frames via a member interface when the frames
    come from another member interface. So when we assign an IP address to
    a member interface, hosts connected to another member interface cannot
    ping to the IP address. That behavior isn't expected. See PR 48104 for
    more realistic examples of this issue.

    The change does:
    - drop M_PROMISC before ether_input, which allows a bridge member interface
      to receive a frame coming from another bridge member interface
    - receive broadcast/multicast frames via all bridge member interfaces,
      which is required to receive IPv6 multicast packets destined to a
      multicast group belonging to a bridge member interface that is different
      from a packet arrival interface

    roy@ helped testing of the fix, thanks!
