This classifier classifies CAN frames (AF_CAN) according to their
identifiers. This functionality can not be easily achieved with
existing classifiers, such as u32. This classifier can be used
with any available qdisc and it is able to classify both SFF
or EFF frames.

The filtering rules for EFF frames are stored in an array, which
is traversed during classification. A bitmap is used to store SFF
rules -- one bit for each ID.

Please resubmit these when the necessary upstream pieces are in Linus's tree.
That will be during the 3.6 merge window.
