general cleanup of the API. The entire API now consists of two functions
similar to the pre-KSE API. The suser() function takes a thread pointer
as its only argument. The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0. The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

- Make sure the interface is UP and RUNNING in fddi_input().
- Reorder and comment packet tests in fddi_input().
- Call if_attach() in fddi_ifattach().
- Test for a valid return from ifaddr_byindex().
- Use struct fddi_header where appropriate.
- Use bcopy() rather than memcpy().
- Use FDDI_ADDR_LEN macro instead of ETHER_ADDR_LEN macro.
- Add loadable module support.
- Use FDDI_ADDR_LEN rather than a magic number or a sizeof().
- Hide distracting sizeof() behind FDDI_HDR_LEN macro.
- Don't use sizeof(struct llc) in areas where we mean LLC_SNAPFRAMELEN.

that causes a machine to panic when the kernel PPP / DEFLATE code is used.
1.11 moved a ZFREE to a point after the structural members were clobbered
by stores into a union'd structure.
This commit fixes the bug and adds a big whopping comment to make sure
the code isn't 'cleaned up' again :-)
Ian Dowse came up with the same patch independantly 68 seconds before I
did, talk about Karma!
I would also like to thank Eugene Grosbein for marathon work in tracking the
problem down by udpating his -stable based on date over and over again
to close in on the commit that caused his crashes.

To enable. Just like ipfw(8) bridging, only input packets are filtered
in the bridge. Filtering works just like in the IP layer, ipf(8)
first, then ipfw(8). And just like in the IP layer, both are
independent, one need not be run to use the other. (Note: This will
not work in, but doesn't break, the bridge.ko module. The ipl.ko
module would need to be fixed before that is worth worrying about.)

currently supported for backwards compatability, but will probably be

New locks are:
- pgrpsess_lock which locks the whole pgrps and sessions,
- pg_mtx which protects the pgrp members, and
- s_mtx which protects the session members.
Please refer to sys/proc.h for the coverage of these locks.
Changes on the pgrp/session interface:
- pgfind() needs the pgrpsess_lock held.
- The caller of enterpgrp() is responsible to allocate a new pgrp and
session.
- Call enterthispgrp() in order to enter an existing pgrp.
- pgsignal() requires a pgrp lock held.

might try and keep using the old address until their arp table

Maybe this ought to be done for INET6 addresses as well but i have
no idea how to do it. It should be pretty straightforward though.

In order of importance:
+ each cluster now uses private data structures (filtering and
local address tables) so you can treat them as fully independent
switches. This part of the work was supported by:
Cisco Systems, Inc. - NSITE lab, RTP, NC.
+ cleaned up the handling of configuration, so the system will behave
much better when real or pseudo devices are dynamically attached
or detached. It should also not panic anymore on systems with large
number of devices, closing a few existings PRs on the topic.
+ while at it, add support for VLAN. This means that a FreeBSD box
can now work as a real VLAN switch, with trunk interfaces etc.
As an example:
ifconfig vlan0 vlan 3 vlandev dc0
ifconfig vlan1 vlan 4 vlandev dc0
net.link.ether.bridge_cfg="vlan0:3,dc1:3,vlan1:4,dc1:4"
uses dc0 as a trunk interface, and dc1 and dc3 as ports on vlans 3 and 4
You get the idea...
NOTA BENE: by default bridge_cfg is initialised to "" so even if
you enable bridging, no packets will be bridged until you set the
list of interfaces on which you want this to happen.
+ large restructuring of the code, moving private vars and types from
bridge.h to bridge.c.
+ added a lot of comments to the code to explain how to use it.
64-bit platforms. The unaligned access is caused by struct ifa_msghdr
not being a multiple of 8-bytes in size. If an interface has an odd
number of addresses, this causes the next interface to generate an
unaligned access in the user-level app walking the interfaces (ifconfig).
