scsi: aacraid: Implement DropIO sync command
IOP_RESET takes a long time to complete. If controller is in a state
where we can bring it back with init struct, send a DropIO sync command
instead.
- If controller is faulted perform standard IOP_RESET in aac_srcv_init.
- If controller is not faulted get adapter properties and extended
properties.
- Update the sa_firmware variable and determine if DropIO request is
supported.
- Issue DropIO request, and get the number of outstanding commands.
- If all commands are complete with success (CT_OK), consider IOP_RESET
is complete.
- If any commands timeout, Perform the IOP_RESET.
