longjmp. I suspect that the occasional double panic may be the result
of incorrect parameters to longjmp. This happens, of course, like the
entire file, only with -DVINUMDEBUG.
give_sd_to_plex: Don't set Raid-5 subdisk state here.
config_subdisk: handle the name parameter correctly when the subdisk
was referenced in a previous plex definition. The
name parameter must come first.
Handle autosizing relatively correctly. There is
still a danger of losing drive space if problems
occur with an autosized subdisk.
Set state to empty, not up, when complete. This also
solves a nagging problem about enforcing the need to
initialize RAID-5 plexes.
config_plex: handle the name parameter correctly when the plex
was referenced in a previous volume definition. The
name parameter must come first.
Handle initial state better.
update_plex_config:
Calculate the trim factor for RAID-5 plexes correctly.
Set the number of down subdisks correctly when reading
from disk config.
Remove comments about not being able to unload from the command line.
Add another example configuration output.
Clarify when to use 'vinum start' and when to use 'vinum read'.
subdisks in need of revival.
vinum_stop: sleep for a second before unloading. This solves a race
condition with a potential daemon when the stop command
is specified on the command line.

This code includes lots of stuff for verbose probing. I'm not 100%
sure that the output of the verbose probe is correct, but everything
else works fine, and -CURRENT was broken for the 5591 before, so I'm
committing it anyway.

Note: the PNIC ignores the lower few bits of the RX buffer DMA address,
which means we have to add yet another kludge to make it happy. Since
we can't offset the packet data, we copy the first few bytes of the
received data into a separate mbuf with proper alignment. This puts
the IP header where it needs to be to prevent unaligned accesses.
Also modified the PNIC driver to use a non-interrupt driven TX
strategy. This improves performance somewhat on x86/SMP systems where
interrupt delivery doesn't seem to be as fast with an SMP kernel as
with a UP kernel.
if uio->uio_offset != -1. This fixes a problem with aio_read/write
and permits a straightforward implementation of pread/pwrite.
