[Cerowrt-devel] trivial 6in4 fix(?)

[Dave Taht]

I don't think I pushed out the 6in4 patch into the build. Hell, I
forgot to tag it too. Remind me to take a vacation next vacation?

If these patches aren't in your build, it looks like we are indeed
only using one class for fq_codel 6in4 traffic and thus are reverting
to nearly pure codel behavior rather than fq_codel.

I might be getting good at reading the patterns here - it looks like
this is fq_codel rather than nfq_codel?

#       target/linux/generic/patches-3.8/677-flow_dissector-Add-6in4-support-to-hash-keys.patch
#       target/linux/generic/patches-3.8/678-Handle-encapsulated-ipv6-better.patch
#       target/linux/generic/patches-3.8/678-remove-bad-timeout-logic-in-fast-recovery.patch

as

tc -s class show dev ge00 output during the test seems to show only one or two
tc classes in use.

But a better test if you are using simplest.qos, rather than
simplest.qos, would be the 4BE test.
