Fix them by enclosing these routines under #ifdef,endif.

This is not a useful configuration. It might make more sense to make NET_DSA a hidden option and have the DSA drivers (in drivers/net/dsa) select it rather than depending on it.
I don't have any idea about net/dsa/***. I just wanted to fix this awkward looking warning :) What i understood from your comment is: Atleast one of the tagging formats must be always enabled if we want to use net/dsa/ stuff ??
And so the functions i have enclosed under ifdefs will always be used if net/dsa/ is used.
And so, if we select NET_DSA from these tagging drivers, then only slave.c will get compiled. Otherwise slave.c dsa.c dsa_core.c wouldn't be compiled and so no warnings.
Correct??
