[PATCH] USB: pegasus & mii cset

  Some ethernet drivers other than those in .../drivers/net need generic
  MII code too and this cset shows how we do it for .../drivers/usb/net;
  For now only pegasus.c is using this feature, but as soon as we find
  more MII compliant controllers we'll put them in Makefile.mii too.
  Note: drivers which use the generic mii routines should bracket the
  code with #ifdef CONFIG_MII #endif since CONFIG_MII may not be present.
  See pegasus.c for more details.
