action of 32 or higher with an INVALID FIELD IN COMMAND specifying

7485	Note that this is not a generic "there's an invalid field in the command", but is specifically saying that the RSO_OPTIONS field in the cdb->options byte is invalid.

sys/cam/ctl/ctl.c
7439	Should "field" be 4 for REQUESTED SERVICE ACTION instead of 1 for SERVICE ACTION?

7439	Sigh, yes, and actually, it needs to be ignored for RSO_OPTIONS_ALL and RSO_OPTIONS_OC so I need to revisit this a bit.

sys/cam/ctl/ctl.c
7439	This should now be fixed.
7494–7495	Removing the SA5 check here is on purpose, for the ASA case both with and without SA5 is fine and is handled below.
