IB/cma: Send MRA for reply messages
Current implementation of RDMA_CM sends MRA (Message Receipt
Acknowledgment) only for request messages but not for response messages.
As a result, a slow active side of the connection may send a ready-to-use
message to the passive side in a delay that is too long for the passive
side to wait for.
This patch adds a call to ib_send_cm_mra() upon receiving a response
message and by this tells the other side to modify the service timeout
to a bigger value, 16 times than before. As in the request case, MRA
for reply will be sent only if a duplicate response has arrived.
