The IB CM (Connection Manager) is used for the connection establishment,
it has nothing do to with Congestion Management. I mentioned it in the
context of IB MAD (Management Datagrams) support by IBoE. I believe that
the RXE driver (IBoE hw emulation on regular Eth nics) emulates mads for
the CM to work.

I believe that IB CCA is not the correct path to go, but rather QCN
which you've mentioned.
