This work sort of clashes with the work that Paul Blakey and I are
doing to integrate conntrack with tc and vice-versa.

Considering that in this patch the action is not RCU-ified, that it is
using a struct as netlink parameter and it is dealing only with the
dscp info, seems it's easier if we/you extend our code to support this
feature as well.  How does that sound to you?

The RFC I had posted is VERY outdated (message-id
cover.1548285996.git.mleitner@...hat.com), please don't use it as
reference.  Not sure if Paul can post a refreshed RFC already.

Thanks,
Marcelo
