- Use the %jd format and a cast to intmax_t to print an int64_t.
- The return type of getopt() is an int, not a char.
This fixes some warnings but there's still much more work to do here.

in the process. This is required for proper debugging of corefiles
created by 1:1 or M:N threaded processes. Add an XXX comment where
we should actually call a function that dumps MD specific notes.
An example of a MD specific note is the NT_PRXFPREG note for SSE
registers.
Since BFD creates non-annotated pseudo-sections for the first PRSTATUS
and FPREGSET notes (non-annotated in the sense that the name of the
section does not contain the pid/tid), make sure those sections describe
the initial thread of the process (i.e. the thread which tid equals the
pid). This is not strictly necessary, but makes sure that tools that use
the non-annotated section names will not change behaviour due to this
change.
The practical upshot of this all is that one can see the threads in
the debugger when looking at a corefile. For 1:1 threading this means
that *all* threads are visible.

is twofold:
1. When a 1:1 or M:N threaded process dumps core, we need to put the
register state of each of its kernel threads in the core file.
This can only be done by differentiating the pid field in the
respective note. For this we need the tid.
2. When thread support is present for remote debugging the kernel
with gdb(1), threads need to be identified by an integer due to
limitations in the remote protocol. This requires having a tid.
To minimize the impact of having thread IDs, threads that are created
as part of a fork (i.e. the initial thread in a process) will inherit
the process ID (i.e. tid=pid). Subsequent threads will have IDs larger
than PID_MAX to avoid interference with the pid allocation algorithm.
The assignment of tids is handled by thread_new_tid().
The thread ID allocation algorithm has been written with 3 assumptions
in mind:
1. IDs need to be created as fast a possible,
2. Reuse of IDs may happen instantaneously,
3. Someone else will write a better algorithm.
Add in missing case for i845G in the attach routine. I'll MFC this

Under polling(4), we counted non-existent output packets and wasted
CPU cycles, corrected. (PR kern/64975.)
The fix in revision 1.71 to correct resetting of the watchdog timer
was wrong.
In rl(4), the TX list does not have a gap between the consumer and
producer, so the "empty TX list" test was wrong, corrected.
Also, resetting the timer to five each time we know there is still
some TX work to do was a bad idea -- under polling(4), if the chip
goes out to lunch, this results in the watchdog routine to _never_
be called. Instead, let the timer downgrade to zero and fire the
watchdog, then reset it to five when it is zero AND there is some
TX work left. (Most other network drivers need this fix too.)

Moved the RX ring resyncing code to ste_rxeoc(), and only run it
if we were asked to POLL_AND_CHECK_STATUS, under DEVICE_POLLING.
(This significantly reduces the CPU load.)
Improved the RX ring resyncing code by re-checking if the head
is still empty before doing resyncing. This mostly affects the
DEVICE_POLLING mode, where we run this code periodically. We
could start checking with an empty head (well, an empty ring
even), and after doing a few iterations, the chip might write
a few entries, including the head, and we would bogusly consider
this case as requiring resyncing. On a test box, this reduced
the number of resyncs done by a factor of 10.
In ste_txeof(sc), only reset the watchdog timer to zero when
the TX list is completely empty.
Converted ste_tx_prev_idx to a pointer -- faster.

to hold the results of scanned ap's but for ibss scans left nodes w/o any
driver-private state setup and/or a bad refcnt (when the nodes were timed
out they were prematurely discarded). Now we treat nodes identified for ap
scanning as before but force nodes discovered when scanning for ibss neighbors
to have complete/proper state and hold the refcnt on the node. Any other
nodes created because of these frames are discarded directly (need to optimize
this case to eliminate various work that's immediately discarded).

nodes in the table have a correct refcnt and driver-private state but is

separate commit).

o add ieee80211_find_txnode routine to lookup a node by mac address and
if not present create one when operating in ibss/ahdemo mode; new nodes
are dup'd from bss and the driver is told to treat the node as if a new
association has been created so driver-private state (e.g. rate control
