jdc 99807188f8 Use m_copydata(), m_adj() and M_PREPEND() to manipulate mbuf's in
bridge_ipf().  Fixes kernel memory corruption that occured when using
m_split() and m_cat().
Idea from OpenBSD.

jdc 32263965e2 Add a flag parameter to bridge_enqueue() to tell it whether to run the
filter or not.  We only need to run the filter for bridge_forward() and
bridge_broadcast().  If we also run it for bridge_output(), we will run
the filter twice outbound per packet, so don't.

In bridge_ipf(), make sure we don't run m_cat() on a single mbuf chain
by checking to see (and remembering) if we need to m_split() the mbuf.
This fixes bridge + ipfilter on sparc.

Fixes PR kern/22063.

jdc e8e38ce54c Include opt_inet.h to get INET6 definition.
Now, bridged ipv6 packets are passed through ipfilter.
However, some v6 packets still do not get transmitted when ipf is enabled.
Partial fix for PR kern/22063.

bouyer 4a3c894eef Fix 2 bugs:
- initialise stp when the bridge is turned up, without this stp will keep
  all interfaces disabled in a sequence like:
  brconfig bridge0 add if0 add if1 stp if0 stp if1 up
- s/BRDGSPRI/BRDGSIFPRIO in brconfig.c:cmd_ifpriority()

add a command (ifpathcost) to change the stp path cost of the STP path cost of
an interface. Display the interface path cost with the others STP parameters.

perseant eab869e1c0 Make BRIDGE_IPF an option, and document it. Add it (commented) to GENERIC.
Let brconfig tell whether the bridge is using the ipfilter hook, or not.

perseant 6b857c229e Add ipf packet-filtering option to if_bridge. The option is controlled at
compile-time by BRIDGE_IPF, and at runtime by brconfig with the {ipf,-ipf}
option on a per-bridge basis.

As a side-effect, add PFIL_HOOKS processing to if_bridge.

martin f54ddc3c17 Add a function to lookup bridge members by struct ifnet * and use
it at all call sites that have such a pointer readily available.
This avoids unnecessary strcmp()s in critical paths, and removes
some XXX comments.

thorpej a180cee23b Pool deals fairly well with physical memory shortage, but it doesn't
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.

thorpej 460da35f85 Add support for building Ethernet bridges, based on Jason Wright's
bridge driver from OpenBSD, although the bridge code has been *heavily*
modified by me (the 802.1D code remains mostly unchanged from the
original).
