Hi Florian

I was trying to keep it KISS, no dynamic memory allocation.

But i can make it more complex. For a tag driver with a single set of
ops, i can probably hide it all in the boiler plate, and make it all
static memory. For tag_brcm.c and tag_ksz.c, which have two ops
structures, i'm not sure i can hide it all.

I will think about it.

	Andrew
