Mark Johnston d862b165a6 bridge: Add support for emulated netmap mode 
if_bridge receives packets via a special interface, if_bridge_input,
rather than by if_input.  Thus, netmap's usual hooking of ifnet routines
does not work as expected.  Instead, modify bridge_input() to pass
packets directly to netmap when it is enabled.  This applies to both
locally delivered packets and forwarded packets.

When a netmap application transmits a packet by writing it to the host
TX ring, the mbuf chain is passed to if_input, which ordinarily points
to ether_input().  However, when transmitting via if_bridge,
bridge_input() needs to see the packet again in order to decide whether
to deliver or forward.  Thus, introduce a new protocol flag,
M_BRIDGE_INJECT, which 1) causes the packet to be passed to
bridge_input() again after Ethernet processing, and 2) avoids passing
the packet back to netmap.  The source MAC address of the packet is used
to determine the original "receiving" interface.
