John Fastabend	82a470f111	net: sched: remove tcf_proto from ematch calls This removes the tcf_proto argument from the ematch code paths that only need it to reference the net namespace. This allows simplifying qdisc code paths especially when we need to tear down the ematch from an RCU callback. In this case we can not guarentee that the tcf_proto structure is still valid.

net: sched: remove tcf_proto from ematch calls

This removes the tcf_proto argument from the ematch code paths that
only need it to reference the net namespace. This allows simplifying
qdisc code paths especially when we need to tear down the ematch
from an RCU callback. In this case we can not guarentee that the
tcf_proto structure is still valid.

net: em_canid: remove useless statements from em_canid_change

tcf_ematch is allocated by kzalloc in function tcf_em_tree_validate(),
so cm_old is always NULL.

net: em_canid: Ematch rule to match CAN frames according to their identifiers

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.
