The hidden patch is not necessary with current kernels and arpfilter.

arp_filter doesn't work.
If I'm not wrong it's applied when you have two or more interfaces in the same subnet. This is not the case.

I have applied hidden patch and it works.

It does not break anything because it's all configurable in /proc.

Maybe it would be good including it in the kernel package?
