+ A variety of 23XX changes:
disable MWI on 2300
based on function code, set an 'isp_port' for the 2312- it's a
separate instance, but the NVRAM is shared, and the second port's
NVRAM is at offset 256.
+ Enable RIO operation for LVD SCSI cards. This makes a *big* difference
as even under reasonable load we get batched completions of about 30
commands at a time on, say, an ISP1080.
+ Do 'continuation' mailbox commands- this allows us to specify a work
area within the softc and 'continue' repeated mailbox commands. This is
more or less on an ad hoc basis and is currently only used for firmware
loading (which f/w now loads substantially faster becuase the calling
thread is only woken when all the f/w words are loaded- not for each
one of the 40000 f/w words that gets loaded).
+ If we're about to return from isp_intr with a 'bogus interrupt' indication,
and we're not a 23XX card, check to see whether the semaphore register is
currently *2* (not *1* as it should be) and whether there's an async completion
sitting in outgoing mailbox0. This seems to capture cases of lost fast posting
and RIO interrupts that the 12160 && 1080 have been known to pump out under
extreme load (extreme, as in > 250 active commands).
+ FC_SCRATCH_ACQUIRE/FC_SCRATCH_RELEASE macros.
+ Endian correct swizzle/unswizzle of an ATIO2 that has a WWPN in it.
