[LARTC] Filtering packets with U32

[openings]

hi.

I want to filter packets that's source address is 192.168.0.1 or 192.168.0.25 or 192.168.0.0/28.

# tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip src 192.168.0.1 flow id 1:30
# tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip src 192.168.0.25 flow id 1:30
# tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip src 192.168.0.0/28 flow id 1:30

But the above command need to execute tc   three times.

Can I filtering it with one line tc command?ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿË\x01\x14™¨¥Šx%ŠË\x7f,\x04S\vùšŠYšŸ÷lõ¯ç–^[m§ÿÿ™¨¥™©ÿvÏZþy\x7f™¨¥™©ÿ–+-ŠwèþV«µÁÎY3ÿ†Ûiÿÿåj»\þŠà

You can try -batch switch. It takes a file to pasrse and run commands from
there. So, you can run once tc command...
