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.
