<DIV><FONT face=Arial size=2>I'm trying to change the code in order to do a RDMA
READ or WRITE to the remote side.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I changed these things:</FONT></DIV>
<DIV><FONT face=Arial size=2>1.create the MR with access_<FONT size=2>ctrl =
IB_AC_LOCAL_WRITE | IB_AC_RDMA_READ | IB_AC_RDMA_WRITE;</FONT></FONT></DIV>
<DIV><FONT face=Arial size=2>2.In the "CM" protocol to exchange the vaddr
(sent as uint64_t) and rkey of the MR, and to exchange data after creation
of the MR;</FONT></DIV>
<DIV><FONT face=Arial size=2>3.<FONT size=2>in the creation of the send
WR:</FONT></FONT></DIV>
<DIV><FONT face=Arial size=2><FONT size=2>send_wr.wr_type = config.xfer_type; //
(WR_RDMA_READ/WRITE)</FONT></FONT></DIV>
<DIV><FONT face=Arial size=2><FONT color=#0000ff size=2>if</FONT><FONT size=2> (
