* Allocate commands on-demand.
* Update a bunch of constants and some structures.
* Use __attribute__ ((__packed__)) instead of __packed to be consistent.
* Support more commands for devices that can apparently handle them.
* Support a "new comm. interface" present in more recent Adaptec
firmware. This reduces the amount of PCI bus traffic in handling
commands.
* Support larger commands going to the adapter--if the adapter can
support them.
* Support 64-bit commands for archs where sizeof(bus_addr_t) > 4 and
for adapters that advertise SGMAP64.
* Handle the WINDOW4G option and NO4GB quirk by excluding 2G-4G window
unless we have the WINDOW4G capability without the NO4GB quirk.
* Ask the adapter more about its capabilities and try to use those if
they seem sane.
* Do our bus_dmamap_sync() inside dequeue_fib instead of following,
since we have the information that we need there.
* Provide access functions for some adapters that I haven't seen yet
(MIPS-based "Rocket" adapters). Not yet used.
with aif_get_mailbox(). Make it return uint32_t instead of 'int'.
* Add an AAC_GET_MAILBOX() macro and change AAC_GET_MAILBOXSTATUS() to use
that.
* Update the Dell PERC 2QC quirk code to use AAC_GET_MAILBOX instead of the
StrongARM-specific code. While StrongARM access is correct for that card,
it's a bad example of how to access the mailbox registers.
* Add the GETINFO command and use it to get and display the card's
supported options at a verbose level during attachment.
