Yes, I've been entrenched in several side projects.  I have a beta 9
ready for release which includes Christoph's patches as well as a
couple of other changes as a result of his comments (qla_fo.cfg,
exioct.h dependencies).  At this time though, I need to wait to
release until I receive another firmware drop.

Yes, given the structure and form of recent patches, that certainly
does seem to be the case - which from QLogic's standpoint (now) seems
to be the proper path.  Just for clarification, given the structure of
the driver now (failover completely separated), inclusion of the
qla2xxx driver would exclude the following failover files:

	qla_fo.c qla_foln.c qla_cfg.c qla_cfgln.c

correct?

Are you proposing to standardize a transport by which a user-space
application communicates with a driver (beyond IOCTLs), or, are you
suggesting there be some commonality in functional interfaces (i.e.
SNIA) for all FC drivers?

Look, IOCTLs were mainly used and built upon due the platform agnostic
nature of the interface.  All QLogic drivers (Linux, Solaris, Windows,
and Netware), use the platform's IOCTL interface with the QLogic
specific EXIOCT interfaces to pass information to/from user and driver
space.  Several user-space APIs were then created which use the EXIOCT
interface, SNIA (or HBAAPI), and several internal APIs, which are
ultimately used by all QLogic applications.
