Marius Strobl 14013280b2 - Although it doesn't make a whole lot of sense to enable RX and TX
before their initial configuration is done, it turns out that r281337
  has the inverse effect on some older chips. Moreover, as with newer
  chips before, two chips seemingly identical according to their MAC
  revisions may behave differently in this regard, with most working
  but a few not, making changes extremely hard to test.
  Closer inspection of the corresponding Linux code suggests that RX
  and TX should only be enabled after their initial configuration with
  RTL8168G and later chips, i. e. RTL8106E{,US}, RTL8107E, as well as
  RTL8168{EP,G,GU,H}, so limit the new code path to these. [1]
- Distinguish between RTL8168H and RTL8107E, with the latter being the
  10/100-Mbit/s-only variant of the former.
- For MAC variants that can only do Fast Ethernet at a maximum, ensure
  that we don't advertise Gigabit Ethernet speed.
- In re_stop(), do the inverse of re_init_locked() and enable RXDV
  gate on RTL8168G and later chips again, matching what Linux does.
