CP-168U board. It initializes and attaches in the same way as the
older (but higher performance) C168H. The only difference is the
board ID, which is 0x1681.

files is usually the first direct block pointer. Since FreeBSD does
automatic block reallocation to reduce filesystem fragmentation, the
file being tailed can be relocated to different blocks 'on-the-fly',
making the check for st_rdev unreliable. The result of this bug is
tail -F pseudo-randomnly thinking the file was rotated when it wasn't,
and as a result, spews out the entire file trying to catch up.

the Palm device and the USB host controller deadlock. The USB host
controller is expecting an early-end-of-transmission packet with 0
data, and the Palm doesn't send one because it's already communicated
the amount of data it's going to send in a header (which ucom/uvisor
are oblivious to). This is the problem that has been known on the
pilot-link lists as the "[Free]BSD USB problem", but not understood.

multi-fragment transmission. I'm not sure if this is a bug or a requirement
that I overlooked with going through the documentation, but the sample
8169 NIC that I have seems to require it at least some of the time or
else it botches TCP checksums on segments that span multiple descriptors.

a problem where the ic_bss node was not being created properly
for the ath driver causing the driver to scribble on random memory.

rate set element id from an AP. This allows stations to associate with
AP's that violate the 802.11 spec by sending >8 rates. This corrects a
recent regression; older code did likewise.

Alexander Kabaev will likely do the equivalent for the other list
types, but I just happened to have this one sitting in a local
non-FreeBSD tree already.
segments are lost for the application. This broke, for example,
ports/benchmarks/dbs which needs the SYN segment to filter the
contents of the trace buffer for the connection it is interested in.
This patch makes the SYN segments available again. Unfortunately they
are now associated with the listening socket instead of the new one, so
a change to applications is required, but without this patch it wouldn't
work altogether.

code has rotten a bit so that the header length is not correct at
the point when tcp_trace is called. Temporarily compute the correct
value before the call and restore the old value after. This makes
ports/benchmarks/dbs to almost work.

in tcp_input that leave the function before hitting the tcp_trace
function call for the TCPDEBUG option. This has made TCPDEBUG mostly
useless (and tools like ports/benchmarks/dbs not working). Add
tcp_trace calls to the return paths that could be identified in this
maze.

in user space or kernel space. VM_MIN_KERNEL_ADDRESS starts after the
gateway page, which means that improper memory accesses to the gateway
page while in user mode would panic the kernel. Use VM_MAX_ADDRESS
instead. It ends before the gateway page. The difference between
VM_MIN_KERNEL_ADDRESS and VM_MAX_ADDRESS is exactly the gateway page.
move to ar.rsc. The RSE must be in enforced lazy mode when writing
to RSE modifyable registers. In this case we restore the RSE NaT
collection register ar.rnat. I have seen 2 general exception faults
on pluto1 now that indicate that the move to ar.rsc has already
happened prior to the move to ar.rnat, meaning that the RSE is not
in enforced lazy mode anymore. The ia64 dependency and instruction
ordering rules seem to allow having both registers written to in
the same instruction group, provided ar.rsc is written to later than
ar.rnat (based on the ordering semantics). It appears that we may
be pushing our luck. For now, put them in seperate cycles (by means
of the instruction group break). If we ever get a general exception
fault on the move to ar.rnat again, we have definite proof that
something else is fishy.
