Thanks, I have split it in parts. The serie should be available shortly at:

git://git.kernel.org/pub/scm/linux/kernel/git/romieu/netdev-2.6.git r6040

Please note that:
1. TIMER_WUT has been removed as it was not used any more
2. I have kept the difference below. Was the patch really supposed to update
   the same error counter twice ?
