10eb0f013c [SCSI] iscsi: pass ep connect shost
When we create the tcp/ip connection by calling ep_connect, we currently
just go by the routing table info.

I think there are two problems with this.

1. Some drivers do not have access to a routing table. Some drivers like
qla4xxx do not even know about other ports.

2. If you have two initiator ports on the same subnet, the user may have
set things up so that session1 was supposed to be run through port1. and
session2 was supposed to be run through port2. It looks like we could
end with both sessions going through one of the ports.

Fixes for cxgb3i from Karen Xie.

f62d0896e6 [SCSI] cxgb3i: Outgoing pdus need to observe skb's MAX_SKB_FRAGS
Need to make sure the outgoing pdu can fit into a single skb.  When
calulating the max. outgoing pdu payload size, take into consideration
of
- data can be held in the skb's fragment list, assume 512 bytes per
  fragment, and
- data can be held in the headroom.

- resize the work-request credit array to be based on skb's MAX_SKB_FRAGS.
- split the skb cb into tx and rx portion
- increase the default transmit window to 128K.
- stop queueing up the outgoing pdus if transmit window is full.

73c3367403 [SCSI] cxgb3i: remove use of skb->sp
The cxgb3i was using skb->sp pointer for some internal book-keeping
which is not related to the secure path. Changed it to use skb->cb[]
instead.

c3673464eb [SCSI] cxgb3i: Add cxgb3i iSCSI driver.
This patch implements the cxgb3i iscsi connection acceleration for the
open-iscsi initiator.

The cxgb3i driver offers the iscsi PDU based offload:
- digest insertion and verification
- payload direct-placement into host memory buffer.
