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.

dd0af9f94e [SCSI] cxgb3i: fix can_queue and cmd_per_lun initialization
cxgb3i was setting can_queue to only 128 commands, and was
setting the can_queue and cmd_per_lun to the same value.

This sets the can_queue to 1024 commands, and sets the cmd_per_lun
to a safer default of 32.

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.
