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.
