Subject: [rft] r8169: merge release 6.001.00 of Realtek's driver - take #1
Untested, straight from the "release early" dept. You have been warned.
Realtek's driver restricts itself to 0x8169 and 0x8167.
It won't be surprising if it breaks on anything else until
I merge the new 0x8168 and 0x8136 bits.
