    [SCSI] libiscsi, bnx2i: make bound ep check common · 661134ad
    Mike Christie authored
    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.
