[PATCH 1/7] qla4xxx: Allow removal of failed session using logout.

[adheer.chandravanshi]

From: Adheer Chandravanshi <adheer.chandravanshi@qlogic.com>

If logout is performed on a failed session entry then that session
should be gracefully removed.

Is this the same as the iscsi max and min from the iscsi spec? If so, it
should be a iscsi host setting.

I think some of these should be common operations instead of vendor ones.

What info does this provide?

Does this set the networking info?

What does this do? Disable the networking?

What does this do? Get the default DDB settings?

RE: [PATCH 0/7] qla4xxx: Updates for scsi "misc" branch

[Lalit Chandivade]

Hi James,

Some of the interfaces like about firmware we can make generic.
And we are still discussing internally, if we can really make the Address Control Block (ACB) interface generic or not.

May be we will re-submit the patches without the ACB (which is still under discussion) in next week.

Thanks,
Lalit.
