[BUG] 2.6.29-rc7 broke r8169 MAC on Thecus n2100 ARM board

From: Mikael Pettersson <hidden>
Date: 2009-03-09 20:29:23

With the 2.6.29-rc7 kernel I'm unable to 'ifup' eth0 on my ARM-based
Thecus n2100 NAS box, which has an RTL8169 NIC (10ec:8169 (rev 10)).
A diff of the kernel logs from 2.6.29-rc6 and -rc7 shows that -rc7
first mangles and then zaps the MAC addresses:

Can you apply the attached patch and see if it fixes any of these
problems ?

Tim, could you give it a try too ? It applies with "patch -p1" from
the kernel tree directory.
