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.
This escaped because DEVICE_POLLING is disabled in LINT being
not compatible with SMP. In fact, it is only a runtime problem,
so if we could recognize that we are building a LINT kernel
we could as well disable the check for SMP being defined.

The new pmap.c is based on NetBSD's newer pmap.c (for the mpc6xx processors)
which is 70% faster than the older code that the original pmap.c was based
on. It has also been based on the framework established by jake's initial
sparc64 pmap.c.
There is no change to how far the kernel gets (it makes it to the mountroot
prompt in psim) but the new pmap code is a lot cleaner.

To negate most of the performance impact I've also enabled
WITNESS_SKIPSPIN. I've done this as we've been running WITNESS
over the spinlock code for a while without incident and it goes a
long way to making the performance problems of WITNESS much more
bearable.
Users who should be running current should know about turning WITNESS
off for performance reasons.
That said and done, WITNESS could/should be made into a tuneable,
but we'll leave that as an excersize to those that want to disable
it without a kernel recompile.

o Modify the system call syntax for extattr_{get,set}_{fd,file}() so
as not to use the scatter gather API (which appeared not to be used
by any consumers, and be less portable), rather, accepts 'data'
and 'nbytes' in the style of other simple read/write interfaces.
This changes the API and ABI.
o Modify system call semantics so that extattr_get_{fd,file}() return
a size_t. When performing a read, the number of bytes read will
be returned, unless the data pointer is NULL, in which case the
number of bytes of data are returned. This changes the API only.
o Modify the VOP_GETEXTATTR() vnode operation to accept a *size_t
argument so as to return the size, if desirable. If set to NULL,
the size will not be returned.
o Update various filesystems (pseodofs, ufs) to DTRT.
These changes should make extended attributes more useful and more
portable. More commits to rebuild the system call files, as well
as update userland utilities to follow.

o Add comments about some maybe questionable stuff so I can check later

o Don't allow INTR_TYPE_FAST. Since we are sharing the interrupt between

be shared.
o Add the same workaround for resume that we have in OLDCARD.
o Also, return the error from bus_generic_resume rather than ignoring it.

was introduced. This occured because unlike the previous code,
vn_start_write() doesn't always return a non-NULL mp, as
filesystems may not support the VOP_GETWRITEMOUNT() call. For

properly.

The binary format "bintime" is a 32.64 format, it will go to 64.64
when time_t does.
The bintime format is available to consumers of time in the kernel,
and is preferable where timeintervals needs to be accumulated.
This change simplifies much of the magic math inside the timecounters
and improves the frequency and time precision by a couple of bits.
I have not been able to measure a performance difference which was not
a tiny fraction of the standard deviation on the measurements.
this is a low-functionality change that changes the kernel to access the main
thread of a process via the linked list of threads rather than
assuming that it is embedded in the process. It IS still embeded there
but remove all teh code that assumes that in preparation for the next commit
which will actually move it out.
