[Cerowrt-devel] a bit of kernel hacking for ipv6 encapsulation on skb_flow_dissector?

I have been fiddling with WAY too many things simultaneously. At the
moment, for example, I'm poking into why transmission doesn't successfully
set the tos field on utp packets while waiting for a profile enabled build
for the tplink while doing a bunch of other things.
While doing that I saw that fq_codel's treatment of IPv6 through a 6in4
tunnel didn't appear to be doing the "right thing", that ipv4 was
outcompeting it left and right.
It looks like the skb_flow_dissector doesn't "do the right thing" on proto
41 (6in4), where it should peel off the ipv4 header and look inside it for
the ipv6 5 tuple. It does do the right thing for GRE... anybody want to
take a stab at fixing
