skb->sk_iif is used as 'incoming interface', skb->dev is 'outgoing interface'.

Since ipset is usually called from netfilter, the ematch

linear area and also sets skb->data to the IP header (otherwise

net: em_canid: Ematch rule to match CAN frames according to their identifiers 2012-07-04T11:07:05+00:00 Rostislav Lisovy lisovy@gmail.com 2012-07-04T03:32:03+00:00 f057bbb6f9ed0fb61ea11105c9ef0ed5ac1a354d This ematch makes it possible to classify CAN frames (AF_CAN) according to their identifiers. This functionality can not be easily achieved with existing classifiers, such as u32, because CAN identifier is always stored in native endianness, whereas u32 expects Network byte order.
