Unfortunately this patch has been created backwards: diff -u file.new file.old when it should be created from diff -u ./drivers/net/r8169.c.old \ ./drivers/net/r8169.c
Additionally, your patch was word-wrapped by your email program, which prevents software from importing the patch into a kernel source tree.

Let's keep the existing style of code. The other MAC registers are listed in the "0xnn" hexidecimal style.

Is there a better name for this register? :)

While we understand that RealTek may need to support multiple kernel versions, drivers in the official kernel.org kernel typically do not contain compatibility code for older kernel versions.

Can you help us understand this code change? This change appears to disable multicast on these MAC versions.
