tcf_ematch is allocated by kzalloc in function tcf_em_tree_validate(), so cm_old is always NULL. Signed-off-by: Duan Jiong <duanj.fnst@cn.fujitsu.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-07-04net: em_canid: Ematch rule to match CAN frames according to their identifiersRostislav Lisovy
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.
