Subject: Re: [PATCH] Fix kernel unaligned access with r8169 on sparc64

Few things about this patch. It's pretty quick and dirty, more experienced 
people with a better knowledge of the ip stack would certainly do better.
Though the problem was reported with Debian's 2.6.18 kernel, it is also 
present in the 2.6.22-rc6 version.

Without the patch, I can hardly achieve 130Mbits between two sparcs on a 
dedicated r8169 link, with it we can achieve 300 Mbits, though it's not 
purely GigE, it's still three times better. Measures were made using iperf.
