a dedicated thread to maintain overrun count correctly in notification
context. mqueue and aio can use thread pool to do notification
concurrently, the thread pool has lifecycle control, some threads will
exit if they have idled for a while.
Releasing items from the mt_zone can not be done by a simple
uma_zfree() call since mt_zone is allocated with the UMA_ZONE_MALLOC
flag. Use uma_zfree_arg instead and supply the slab.
This bug caused panics in low memory situations on unloading kernel
modules containing MALLOC_DEFINE(..) statements.

Note for MFC: Perhaps the option should stay in RELENG_6 for POLA reasons.

re-organizing the monitor return logic. We perform interface monitoring
checks after we have determined if the CRC is still on the packet, if
it is, m_adj() is called which will adjust the packet length. This
ensures that we are not including CRC lengths in the byte counters for
each packet.

destination interface as a member of our bridge or this is a unicast packet,
push it through the bpf(4) machinery.
For broadcast or multicast packets, don't bother with the bpf(4) because it will
be re-injected into ether_input. We do this before we pass the packets through
the pfil(9) framework, as it is possible that pfil(9) will drop the packet or
possibly modify it, making it very difficult to debug firewall issues on the
bridge.
Further, implemented IFF_MONITOR for bridge interfaces. This does much the same
thing that it does for regular network interfaces: it pushes the packet to any
bpf(4) peers and then returns. This bypasses all of the bridge machinery,
saving mutex acquisitions, list traversals, and other operations performed by
the bridging code.
This change to the bridging code is useful in situations where individuals use a
bridge to multiplex RX/TX signals from two interfaces, as is required by some
network taps for de-multiplexing links and transmitting the RX/TX signals
out through two separate interfaces. This behaviour is quite common for network
taps monitoring links, especially for certain manufacturers.
