o do not override the home channel recorded for the sta when the frame is
received off-channel; this fixes a problem where we might think the sta
was operating on the channel the frame was received on causing association
requests to be ignored/rejected (likely cause of kern/99036)
o don't include rssi of off-channel frames in the avg rssi used to select
a bss; this gives us a better estimate of the signal we will see for the
station when on-channel

silent NULL pointer dereference in the i386 and sparc64 pmap_pinit()
when the kmem_alloc_nofault() failed to allocate address space. Both
functions now return error instead of panicing or dereferencing NULL.
As consequence, vmspace_exec() and vmspace_unshare() returns the errno
int. struct vmspace arg was added to vm_forkproc() to avoid dealing
with failed allocation when most of the fork1() job is already done.
The kernel stack for the thread is now set up in the thread_alloc(),
that itself may return NULL. Also, allocation of the first process
thread is performed in the fork1() to properly deal with stack
allocation failure. proc_linkup() is separated into proc_linkup()
called from fork1(), and proc_linkup0(), that is used to set up the
kernel process (was known as swapper).

default object rather than cache it was to have
vm_pager_has_page(object, pindex, ...) == FALSE to imply that there is
no cached page in object at pindex. This allows to avoid explicit
checks for cached pages in vm_object_backing_scan().
For now, we need the same bandaid for the swap object, otherwise both
the vm_page_lookup() and the pager can report that there is no page at
offset, while page is stored in the cache. Also, this fixes another
instance of the KASSERT("object type is incompatible") failure in the
vm_page_cache_transfer().

- Select a tag gains ability to optionally save new tags
off in the timewait system.
- When looking up associations do not give back a stcb that
is in the about-to-be-freed state, and instead continue
looking for other candiates.
- New function to query to see if value is in time-wait.
- Timewait had a time comparison error that caused very
few vtags to actually stay in time-wait.
- When setting tags in time-wait, we now use the time
requested NOT a fixed constant value.
- sstat now gets the proper associd when we do the query.
- When we process an association, we expect the tag chosen
(if we have one from a cookie) to be in time-wait. Before
we would NOT allow the assoc up by checking if its good.
In theory this should have caused almost all assoc not
to come up except for the time-comparison bug above (this
bug was hidden by the time comparison bug :-D).
- Don't save tags for nonce values in the time-wait cache
since these are used only during cookie collisions and do
not matter if they are unique or not.

changes:
01 - Enhanced LRO:
LRO feature is extended to support multi-buffer mode. Previously,
Ethernet frames received in contiguous buffers were offloaded.
Now, frames received in multiple non-contiguous buffers can be
offloaded, as well. The driver now supports LRO for jumbo frames.
02 - Locks Optimization:
The driver code was re-organized to limit the use of locks.
Moreover, lock contention was reduced by replacing wait locks
with try locks.
03 - Code Optimization:
The driver code was re-factored to eliminate some memcpy
operations. Fast path loops were optimized.
04 - Tag Creations:
Physical Buffer Tags are now optimized based upon frame size.
For better performance, Physical Memory Maps are now re-used.
05 - Configuration:
Features such as TSO, LRO, and Interrupt Mode can be configured
either at load or at run time. Rx buffer mode (mode 1 or mode 2)
can be configured at load time through kenv.
06 - Driver Statistics:
Run time statistics are enhanced to provide better visibility
into the driver performance.
07 - Bug Fixes:
The driver contains fixes for the problems discovered and
reported since last submission.
08 - MSI support:
Added Message Signaled Interrupt feature which currently uses 1
message.
09 Removed feature:
Rx 3 buffer mode feature has been removed. Driver now supports 1,
2 and 5 buffer modes of which 2 and 5 buffer modes can be used
for header separation.
10 Compiler warning:
Fixed compiler warning when compiled for 32 bit system.
