Date: Sat,  9 Apr 2016 18:41:10 +0530	[thread overview]
Message-ID: <cover.1460204441.git.varun@chelsio.com> (raw)

This is v2 patch series for Chelsio iSCSI target offload
driver(cxgbit.ko).

cxgbit.ko registers with iSCSI target transport and
offloads multiple CPU intensive tasks to
Chelsio T5 adapters.

T5 adapters has following offload features for
iSCSI
-TCP/IP offload
-iSCSI PDU recovery by reassembling TCP segments.
-Header and Data Digest offload.
-iSCSI segmentation offload(ISO).
-Direct Data Placement(DDP).

-v2
 - added hw offload transport type (Nicholas).
 - added PDU alloc, free, xmit callbacks (Nicholas).
 - created single patch for all cxgbit.ko files (Nicholas).
 - merged definition and usage of int (*iscsit_validate_params)()
   in a single patch (Christoph).
 - merged definition and usage of void (*iscsit_release_cmd)()
   in a single patch (Christoph).
 - renamed void (*iscsit_rx_pdu)() to void (*iscsit_get_rx_pdu)() (Sagi).  
 - added dependency on INET in Kconfig (Arnd).
 - added check for NULL sg in cxgbit_set_one_ppod() (Dan Carpenter). 

Please review.

Thanks
