ISP23xx and ISP24xx chips have support for an adaptive
method of posting SCSI command completions for multiple SCSI
commands during a single system interrupt.
SCSI commands are placed on the system response queue
without interrupting the host until 1) a delay timer
expires; or 2) a SCSI command completes with an error.
As long as the host software (qla2xxx) services the response
queue for completions (this polling is done during
queuecommand()) within the 'delay timer' period, the
firmware will not generate system interrupt.

Export additional host information via the shost_attrs member in
the scsi_host template. Attributes include: driver version,
firmware version, ISP serial number, ISP type, ISP product ID,
HBA model name, HBA model description, PCI interconnect
information, and HBA port state.

Add ISP24xx ISR routines.
Add appropriate glue-code for ISP24xx support -- this
included generalizing some of the core handling
routines (qla2x00_async_event() [pull-up retrieval of
mailbox values] and qla2x00_status_entry()]. Fixup
2100/2300 ISRs to handle the new conventions.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
