[PATCH rdma-core 12/12] tests: Add XRC ODP test case

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Maxim Chicherin <maximc@xxxxxxxxxxxx>

This case creates client and server, each one have two SEND and RECV
XRC QPs, and SRQ. By connecting SRQ and RECV XRC QPs to the same XRCD
and connecting SEND XRC QPs to RECV XRC QPs of the opposite side,
we run a traffic and validate the data received by the SRQ.
