This doesn't seem like an acceptable solution -- this means that anyone
using a new kernel with older firmware has a broken system.

Can't we just keep track of the current capability mask and make sure to
set it properly when doing the SET_PORT command?

Actually, looking at the code, it seems we really should unify the
multiple mlx4_SET_PORT implementations anyway.
