[openib-general] [PATCH] uverbs rdma example (updated)

[Roland Dreier]

I started looking over this code.  As far as I can see, neither
tx_depth nor rx_depth is used for anything.  Is this correct?  Should
we just get rid of the options?

Also would it make sense to change the RDMA operation to be unsignaled
and just poll the destination buffer (ignore completions)?  I realize
this is a Mellanox extension to the spec but it might be more
interesting than yet another variation on the pingpong code.
