on x86 boxes. There must be a better way to deal with this that works
well for everyone. In the meantime, back out to the version that works
for more people.
Don't decrease/check xs_retries when the device report "Power On, Reset, or
Bus Device Reset" sense condition, just retry the command. The initial bus
reset would cause the first TEST_UNIT_READY to report this condition,
and as xs_retries is set to 0 when XS_CTL_DISCOVERY is set, it would report an
error instead of being retried, causing the disk probe to report "drive
offline" instead of the geometry and capacity. Checking/decreasing
xs_retries on the bus reset reported by the adapter is enouth to avoid the
problem reported by rev 1.102.

to pool_init. Untouched pools are ones that either in arch-specific

Convert struct session, ucred and lockf to pools.
make the `unmatched vendor code' error message slightly more verbose to
make things easier next time this kind of issue arises.

the mode sense request. So fall back on mode sense data including a block
descriptor section.

the PCIX bus start to get heavily loaded. This only happen when using
chained descriptors, therefore work-around it by providing a private
pool of receive buffers able to contain a full-sized packet.
in tsleep()/wakeup() to appease gcc. Otherwise, the ch_flags value may
be cached in a register in atabus_thread(), and when it sets the WDCF_TH_RUN
bit after tsleep() it may loose loose the changes made by an interrupt handler
or another thread.

- Fix jumbo frame support.
- Disable interrupts at the chip in sip_intr().
- Disable checksum offloading if MTU > 8109 - the hardware is broken
in this case.
- Use the interrupt hold-off timer.
- Correct the Tx FIFO size.
- Add Pause Control/Status register definitions.
