  - Allow multiple (external) PHYs with Am79C97{2,6}, which actually
    only support external PHYs (besides not connectable internal ones
    which respond at the usual addresses, but which don't hurt if we
    let them show up) and don't wedge when isolating PHYs. Actually,
    this change special cases limiting PHYs to Am79C97{3,5,8}, for
    which this driver doesn't implement swiching between the internal
    and external PHYs, yet, and Am79C971, where isolating the external
    PHY (at least in case it's a DP83840A) wedges the chip. Together
    with sys/dev/mii/acphy.c rev. 1.21 this adds support for the
    100baseFX port of AT-2700 series adaptors, which use two AC101,
    one for the copper and one for the fibre port (there might be
    variants which only use one PHY though).
  - Fix a bug in the previous revision that prevented the address of
    the used (external) PHY to be actually recorded.
  - Don't bother to set if_mtu to ETHERMTU, ether_ifattach() does that.
