Linux kernel 2.6.12 does not support the 8168 (it includes some 8169 fixes
though).

1. I mean now. See:
   http://www.fr.zoreil.com/people/francois/backport/r8169/20070227-00
   (big patch or serie of 54 pieces).

2. Compiled, untested. You know what you have to do.

3. Due to the changes in the driver, one could hope that the link will be
   autocorrectly set. Please give it a try before using ethtool/mii-tool.

4. The patchkit does not include the latest changes/bugfixes. They are
   still experimental but some users have a poor 8168 experience without
   them. YMMV. Please send a complete dmesg, lspci -vvx and the brand of
   the motherboard if the driver stops working randomly.
