in ICL interface.
- the ordering of parameters to icl_conn_task_setup is different, so that
the "cookie" is last.
- the icl_conn_connected() method is gone, replaced by much simpler mechanism.
I'd rather keep the ICL interface as small as possible.
- I don't really like the s/offload/driver/g. The "tcp" is not a driver;
"iser" is not really a driver either. I'd prefer to leave it as it is.
- the check for ic_session_type_discovery() in iser_conn_handoff() is gone,
as handoff cannot happen for discovery sessions.
- ic_session_login_phase() and ic_session_type_discovery() are gone. If you
had your handoff method called - you're no longer in either of those.
- the way maxtags is passed is different; now it's simply ic->ic_maxtags.
It's cleaner, and the old way would cause weird things to happen if
fail_on_disconnection=1 and the user changed the maxtags sysctl before
reconnecting (basically the CAM idea of maxtags would be different from
iSER one).
- icl_hba_misc() is gone; declare support for PIM_UNMAPPED by setting
ic->ic_unmapped flag.
- the way we find the "iser" ICL module is rewritten - we have a flag
for icl_register() that says if the module is iSER-capable or not.
- icl_conn_release() is gone; iser_conn_release() is called from
iser_conn_free() (no functional change in this case) and at the beginning
of icl_conn_connect(), to handle reconnection.
