This patchset implements support for matching
on PPPoE specific fields using tc-flower.
First patch adds support for parsing ppp protocols
and it also introduces small refactor which allows
to use same mechanism of finding protocol for
both ppp and ether protocols. Second patch
is about parsing PPPoE fields.
