Hi!,
I'm not able to subscrive at this list. My server mail don't send the mail 
and consider it a spam mail...
For this, please send eventual response to this mail address 
(franco.daje@virgilio.it)

The problem is this:
I'm searching, in kernel code, the code that implement thi command:

tc filter add dev eth2 parent ffff: protocol ip prio 1 u32 match ip src 
0.0.0.0/0 police rate $1 burst $2 drop flowid :1

I thought that this code was police.c but seem that it isn't
i must implement a proc file in the code and recompiling the kernel.

Thanks

Franco
