[disclaimer - I'm far from knowledgeable in iscsi ]

I agree that the problem of out-of-order handling is probably generic,
but our solution is very device oriented.
As the device lacks [a lot of] internal memory, it uses the host memory
for out-of-order buffers and the driver assistance in pushing them when
they are needed.
>From driver perspective, all the data is completely opaque; All it does is
follow the firmware's guidance in storing & re-transmitting buffers when
required.

Now, I guess the logic could be divided between hardware-specifics -
Interaction with 'client' [in our case, device's firmware], to receive
new data, instructions regarding placement and re-transmission,
and a lower generic data structure which supports manipulation of
buffers [push-left, push-right, join, etc.].

But given that the data-structure would completely lacks all
protocol-knowledge [as our implementation doesn't have nor require such],
I think there would be very little gain - we might find out that as much
as 80% of the code is device interaction, and the remaining so-called
'generic' data-structure won't be that useful to other clients as it was
closely tied to our device needs and API.

Either way, placing this under iscsi would probably be insufficient for our
future needs, as our qed-iwarp driver would also require this functionality.

Thanks,
Yuval

I see that I can avoid the IS_ENABLED() here as well. I will fix this
in the next revision.

[RFC 2/6] qed: Add iSCSI out of order packet handling.

2016-10-18 Thread manish.rangankar

From: Yuval Mintz 

This patch adds out of order packet handling for hardware offloaded
iSCSI. Out of order packet handling requires driver buffer allocation
and assistance.
