I am doing my graduation project using traffic controller on linux tool
 
but unfortunately the u32 filter command failed to match on the protocol field
 
i used:
 
$TC filter add dev $DEV parent 1:0 protocol ip prio 11 u32 match ip protocol 1 0xff flowid 1:10
and then:
 
$TC filter add dev $DEV parent 1:0 protocol ip prio 11 u32 match u8 0x01 0xff at 9
 
 
and both of them failed , although they worked as a syntex < bash didn't say any error messages > but practically they failed to do the job
 
any comments please
 
I need your help QUICKLY PLEASE
 
THNKS A LOT :)
