SVN rev 198529 on 2009-10-27 21:09:52Z by emaste
MFC r188743,r188940
Use outbound message register 0 instead of mailbox 7 in
aac_{rx,rkt}_get_fwstatus, as done in Adaptec's vendor driver as well as
the Linux drivers.
Submitted by: jkim, from Adaptec's driver
==
SVN rev 188743 modified aac_rx_get_fwstatus to use the AAC_RX_OMR0
register instead of AAC_RX_FWSTATUS, as that is the way it's done in
Adaptec's vendor driver and in the Linux drivers. (The same applies
to aac_rkt_get_fwstatus as well.)
However, a concern has been raised about the compatibility of this
change and old hardware / firmware versions. In the absense of
specific information, revert to the original behaviour if the firmware
does not support the "New comm." interface. Users of old cards or
firmware haven't reported the problems that are potentially solved by
switching to OMR0.
