Firmware semantics changed for 24xx and above ISPs in their
handling of the specified execution-throttle passed during
firmware initialization. The original codes use of a theoretical
maximum (0xffff, as carried over from earlier ISPs) could in fact
act as a throttle in some circumstances. Now set the value based
of the firmware's own 'resource' (exchange IOCBs) capabilities.

The original code to 'resize request-queues' based on iocb-counts
and employed during early ISP23xx testing was too
overly-pessimistic with regards to latencies in the firmware
pulling requests. Recent ISPs can easily keep up processing a
stream of commands from an abbreviated (effectively, half the
original size) queue.

When IRQs are shared by multiple controllers and if the first one
to register does not disable the IRQ, then IRQ will be enabled
for all other controllers by default, irrespective of their
setting. With IRQF_DISABLED registration, the driver interrupt
routine was called with interrupt enabled always. Disbaling the
registration with IRQF_DISABLED, since driver code is re-entrant
safe and all critical sections are guarded with interrupt safe
locks.

Given the low-level interface varies from one flash-part
manufacturer to the next, the Flash-Access-Control (FAC) mailbox
command makes the specific flash type transparent to the driver
by encapsulating a basic set of accessor and update routines.

To ensure smooth operations amongst the FCoE and NIC side
components of the ISP81xx chip, the FCoE driver (qla2xxx) must
ensure the 10gb NIC driver (qlge) does not timeout waiting for
IDC (Inter-Driver Communication) acknowledgments. The
acknowledgment requirements are trivial -- a simple mirroring of
incoming mailbox registers during the AEN to a process-context
capable mailbox command.

Correct response-queue-0 processing by instructing the firmware

now done for all non-0 response queues. Since all
response-queues now run in the same mode, the driver no longer

When clearing the flash device's SR, the comment is incorrect...
clearing the SR is 2 steps:
1. the SR protect bit is 1, so the first write zero clears only
that bit,
2. the SR protect bit is now 0, so the next write zero clears the
remaining bits.
The sector erase debug print more correctly identifies that the erase failed.

to loading this firmware if the request-firmware interface failed
(userspace .bin file). Moving forward, all ISP81XX parts will
