adds bwn(4) driver for supporting Broadcom BCM43xx chipsets.
o uses v4 firmware instead of v3. A port will be committed to
create the bwn firmware module.
o supports B/G and LP(low power) PHYs.
o supports 32 / 64 bits DMA operations.
o tested on big / little endian machines so should work on all
architectures.
It'd not connected to the build until the firmware port is committed.

The same code is used to import and to create pool.
The order of operations is the following:
1. Try to open vdev by remembered path and guid.
2. If 1 failed, try to find vdev which guid matches and ignore the path.
3. If 2 failed this means either that the vdev we're looking for is gone
or that pool is being created and vdev doesn't contain proper guid yet.
To be able to handle pool creation we open vdev by path anyway.
Because of 3 it is possible that we open wrong vdev on import which can lead to
confusions.
The solution for this is to check spa_load_state. On pool creation it will be
equal to SPA_LOAD_NONE and we can open vdev only by path immediately and if it
is not equal to SPA_LOAD_NONE we first open by path+guid and when that fails,
we open by guid. We no longer open wrong vdev on import.
r206051:
IOCPARM_MAX defines maximum size of a structure that can be passed
directly to ioctl(2). Because of how ioctl command is build using _IO*()
macros we have only 13 bits to encode structure size. So the structure
can be up to 8kB-1.
Currently we define IOCPARM_MAX as PAGE_SIZE.
This is IMHO wrong for three main reasons:
1. It is confusing on archs with page size larger than 8kB (not really
sure if we support such archs (sparc64?)), as even if PAGE_SIZE is
bigger than 8kB, we won't be able to encode anything larger in ioctl
command.
2. It is a waste. Why the structure can be only 4kB on most archs if we
have 13 bits dedicated for that, not 12?
3. It shouldn't depend on architecture and page size. My ioctl command
can work on one arch, but can't on the other?
Increase IOCPARM_MAX to 8kB and make it independed of PAGE_SIZE and
architecture it is compiled for. This allows to use all the bits on all the
archs for size. Note that this doesn't mean we will copy more on every ioctl(2)
call. No. We still copyin(9)/copyout(9) only exact number of bytes encoded in
ioctl command.
Practical use for this change is ZFS. zfs_cmd_t structure used for ZFS
ioctls is larger than 4kB.

Provide groundwork for 32-bit binary compatibility on non-x86 platforms,
for upcoming 64-bit PowerPC and MIPS support. This renames the COMPAT_IA32
option to COMPAT_FREEBSD32, removes some IA32-specific code from MI parts
of the kernel and enhances the freebsd32 compatibility code to support
big-endian platforms.
This MFC is required for MFCs of later changes to the freebsd32
compatibility from HEAD.

Add run(4), a driver for Ralink RT2700U/RT2800U/RT3000U USB 802.11agn devices.

- Do not allocate a full tx ring for the offload queue if the card is not
offload capable.
- Slightly better freelist size calculation.
- Fix nmbjumbo4 typo, remove unneeded global variables.

A significant amount of improvements were done by jkim@ during the recent

Hopefully I have stolen all their work to 8-STABLE :)

- Move nfs_realign() from the NFS client to the shared NFS code and
remove the NFS server version in order to reduce code duplication.
The shared version now uses a second parameter how, which is passed
on to m_get(9) and m_getcl(9) as the server used M_WAIT while the
client requires M_DONTWAIT, and replaces the the previously unused
parameter hsiz.
- Change nfs_realign() to use nfsm_aligned() so as with other NFS code
the alignment check isn't actually performed on platforms without
strict alignment requirements for performance reasons because as the
comment suggests unaligned data only occasionally occurs with TCP.
- Change fha_extract_info() to use nfs_realign() with M_DONTWAIT rather
than M_WAIT because it's called with the RPC sp_lock held.

lindev(4) [1] is supposed to be a collection of linux-specific pseudo
devices that we also support, just not by default (thus only LINT or
module builds by default).
While currently there is only "/dev/full" [2], we are planning to see more
in the future. We may decide to change the module/dependency logic in the
future should the list grow too long.
This is not part of linux.ko as also non-linux binaries like kFreeBSD
userland or ports can make use of this as well.

- use dpcpu data to track the ifps with packets queued up,
- per-cpu locking and driver flags
- along with .nh_drainedcpu and NETISR_POLICY_CPU.
- Put the mbufs in flight reference count, preventing interfaces
from going away, under INVARIANTS as this is a general problem
of the stack and should be solved in if.c/netisr but still good
to verify the internal queuing logic.
