I don't mind taking a wack at this if you guys are too busy (I'm rather
tired of seeing the warning across all of my builds). However, I am
wondering how far should this be unwound? Should 'enum opa_mtu' be
collapsed into 'enum ib_mtu' and then all of the opa conversion
functions be eliminated in favor of the ib ones? It looks like
OPA_MTU_8192 and OPA_MTU_10240 are used in a few places within
drivers/infiniband/hw/hfi1, should all of those instances be converted
over to IB_MTU_* and the defines at the top of
drivers/infiniband/hw/hfi1/hfi.h be eliminated?

Cheers,
Nathan
