qed*: Utilize Firmware 8.15.3.0
This patch advances the qed* drivers into using the newer firmware -
This solves several firmware bugs, mostly related [but not limited to]
various init/deinit issues in various offloaded protocols.
It also introduces a major 4-Cached SGE change in firmware, which can be
seen in the storage drivers' changes.
In addition, this firmware is required for supporting the new QL41xxx
series of adapters; While this patch doesn't add the actual support,
the firmware contains the necessary initialization & firmware logic to
operate such adapters [actual support would be added later on].
Changes from Previous versions:
