Hi All,

I have tested the PA Semi Ethernet with the kernels 4.2.3 and 4.3.0 
today. With the kernel 4.2.3 it works but with the kernel 4.3.0 final it 
doesn't work.

After that I tested some git kernels and release candidates of 4.3.

Kernel 4.3 git from Tue Sep 01, 2015 -> PA Semi Ethernet works
Kernel 4.3 git from Wed Sep 02, 2015 -> PA Semi Ethernet works
Kernel 4.3 git from Thu Sep 03, 2015 -> PA Semi Ethernet works
Kernel 4.3 git from Fri Sep 04, 2015 -> PA Semi Ethernet doesn't work 
(Merge tag 'powerpc-4.3-1': 
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ff474e8ca8547d09cb82ebab56d4c96f9eea01ce)
Kernel 4.3 git from Sat Sep 05, 2015 -> PA Semi Ethernet doesn't work
Kernel 4.3 git from Mon Sep 07, 2015 -> PA Semi Ethernet doesn't work
Kernel 4.3 git from Wed Sep 09, 2015 -> PA Semi Ethernet doesn't work
Kernel 4.3 git from Fri Sep 11, 2015 -> PA Semi Ethernet doesn't work
Kernel 4.3 RC1 from Sun Sep 13, 2015 -> PA Semi Ethernet doesn't work
Kernel 4.3 RC2 from Mon Sep 21, 2015 -> PA Semi Ethernet doesn't work

The problematic commit must be between Thu Sep 03, 2015 at 09:37 AM (UTC 
+2) and Fri Sep 04, 2015 at 7:38 PM (UTC +2) in the linux git.
