Re: [LARTC] Filter for large packets?

[Simon Stemplinger <Simon.Stemplinger@gmx.de>]

I figure it should be

tc filter add dev $DEV parent 1: protocol ip prio 10 u32 \
  match ip protocol 6 0xff \
  match u8 0x05 0x0f at 0 \
  match u8 0x04 0x04 at 2 \
  match u8 0x10 0xff at 33 \
  flowid 1:30

but it doesn´t work... what am I doing wrong?

regards,
Simon
