[openib-general] [RFC/PATCH] librdmacm: modify multicast code for RDMA_PS_IPOIB port space

[Or Gerlitz]

Sean,

with one host being both the client and the server, mckey does not work for me even without the
IPOIB PS changes, it used to work between two hosts with the below patch that forces the sender
to generate and poll completions on its TX packets.

please let me know how its going with mckey on your system, i am going to
test the librdmacm patches i have just sent with our mcast app.

Or.
