I think we should just select PCS_LYNX unconditionally from stmmac even if no front-end driver using it is enabled. I tried to come up with a way to move the dependency into the altera specific front-end, but couldn't find an obvious or simple way to do this. Having a proper abstraction for PCS drivers instead of directly calling into exported driver symbols might help here, but that would add complexity elsewhere. Arnd
