firmware to delay completion of commands so that it can attempt to batch
a bunch of completions at once- either returning 16 bit handles in mailbox
registers, or in a resposne queue entry that has a whole wad of 16 bit handles.
Distinguish between 2300 and 2312 chipsets- if only because the revisions
on the chips have different meanings.
Add more instrumentation plus ISP_GET_STATS and ISP_CLR_STATS ioctls.
Run up the maximum number of response queue entities we'll look at
per interrupt.
If we haven't set HBA role yet, always return success from isp_fc_runstate.
