Hmm, it seems that this hardware is newer one as you know. ATM
there are several new gneration of RealTek controllers not
supported by re(4). For instance, RTL8168C, RTL8168CP, RTL8111C
and RTL8111CP.
These controllers seems to use different descriptor formats and
have lots of new magic registers. There are no publicly available
datasheet to BSD developers so it would take long time to get a
stable driver for these controllers. I already tried to contact
RealTek for datasheet but they requested signing NDA which I can't
accept. Some users reported partial success for WIP version but
others still have trouble to get a valid link. It seems that re(4)
need magic for PHY hardwares as Linux. :-(

For 8169 family hardware, re(4) have worked without problems so
far. Since your controller seems to be 8169 family I have no clue
why re_reset() timed out for reset operation. Anyway, here is WIP
version, would you give it a try?

The WIP version was generated against HEAD but I guess it would
apply to RELENG_7 too. You can find the WIP version in the
following URL.
