This removes 288KB (36%) of the driver code and zillions of hacks and workarounds, making single driver uniformly support several different generations of hardware interfaces, not counting minor card variations. After years of the hopeless fight, I don't think it worth to continue support for hardware obsolete for 15-20 years. Instead much cleaner now code should allow to move forward toward better locking, multiple queues and other cool features. All the remaining Qlogic cards starting from 4Gb 24xx to 32Gb 27xx use the same hardware/firmware interface with minor incremental improvements, so it seems to be a good new starting point. Except one PCI-X model all all of them are PCIe and so still usable in modern systems. Discussed with: ken, scottl, jpaetzel, imp Relnotes: yes
