Hello Mike,
The following snippet from the 39d4ceb04f051c208ae7509d268a3871ffa194c5
commit is preventing bnx2i from being able to offload when connecting
through the iscsi_sysfs_get_hostinfo_by_host_no code path where the
session argument == NULL. The initiatorname sysfs inquiry failed but
this is expected since it does not exist in the iscsi_host for bnx2i.
Perhaps the error return code should only be propagated upward when
session != NULL specifically for hbas like qla4xxx?
Thanks,
Eddie

(Well, of course it got line-wrapped, but should get you the idea).
I'll be sending the proper patch to the mailing-list shortly.
But yes, that is a real issue.
Yeah, this is right. That is the behavior we had before. I can just fix
this up and merge it if there were no other changes needed.
Not in this area, no.
I've got some minor patches to the SUSE init script but they still
need further testing.
And actually I'm working on an 'iscsi_offload' scripts which
configures the interface definitions for the various offload
engines. If there is enough interest maybe we should include it in
the open-iscsi tarball.
Cheers,
Hannes
