0. after disconnecting a cable (we just used a switch interface to
disable a port)
for a connected qpair, we get errors when try to send a packet on that
(this is expected). but
1. don't get errors when try to post receive a packet. is this expected?
2. don't get any of the IB_EVENT_CQ_ERR,
IB_EVENT_QP_FATAL, (ib_event_type) errors..
a. when is a good time for ULPs to issue disconnect and destroy qpairs in
such cases? should it do it in step 0? should it expect step 1 and 2 to
b. what is expected when we connect the cable back? I assume for RC QP
we must destroy the connection/QP in case of such error, it will
never come back
to ok state. is that right?
