[ofw] patch 2/2 Add support for RDMAoEth to the low level driver

[James Yang]

I guess that's just one way to make local RDMAoe subnet know that grh must be used and at the same time same code also works in real IB environment. There might be other specifications that i don't know.

Yes - I understand that.  What I don't understand is *why* a path record for
RDMAoE would specify a hop count > 1 to begin with.  That doesn't make sense,
and a can't imagine that an RDMAoE specification would require a hop count > 1
for the local subnet case.  The RDMAoE checks need to be more explicit.
