parent[SCSI] libiscsi: add completion function for drivers that do not need pdu processing (diff)
[SCSI] libiscsi, bnx2i: make bound ep check common
bnx2i currently has a check for if a ep is properly bound, so if iscsi_queuecommand/xmit_task is called while there is no ep we will not queue IO. be2iscsi sends IO from queuecommand/xmit_task like how bnx2i does and needs a similar test. This patch has us just use the suspend_bit test for this. When ep_poll has succeeed iscsid will call conn_bind, the LLD will then call iscsi_conn_bind which will clear the suspend bit. When ep_disconnect is called (or if there is a conn error) we set the suspend bit. For the ep_disconnect case I am adding a helper in this patch that will take the session lock to make sure iscsi_queuecommand/xmit_task is not running and it will set the suspend bit.
