I've had the guess that each driver will need to provide a WC to gid
table entry conversion function..
Ideal hardware driver will report the gid table index in their
internal WC. Other hardware like mlx wil have to parse the WC and the
GRH headers and so forth to figure out the gid table index.
The gid table index is security sensitive, so it *MUST* be determined
exactly and correctly.
But we need to understand what the other rocee drivers have done in
this area..
