+1 Dealing with the busted DSL stuff since 3.8 has been no fun and it would
be nice if these last fixes made it into 3.10.X at least so router/fw
distros can pick them up more easily. The difference in dsl behavior since
the bustage in 3.8 to the saner now is remarkable.

Probably not meeting the criteria for 3.10-stable inclusion (as they aren't
exactly bugfixes) are the tiny improvements to the flow dissector made in
3.11 for better ipip, ipv6 encapsulation, and 802.1ad support, but I
thought I'd mention them so other fq_codel folk pick them up that need them.

Not ready for any tree and increasingly doubtful for 3.12 are some
improvements under test to codel and cisco's sch_pie, if anyone wants to
play with them, let me know off list.
