This work adds a generalization of the ingress qdisc as a qdisc holding
only classifiers. The clsact qdisc works on ingress, but also on egress.
In both cases, it's execution happens without taking the qdisc lock, and
the main difference for the egress part compared to prior version of [1]
is that this can be applied with _any_ underlying real egress qdisc (also
classless ones).

You probably should move qdisc_pkt_len_init() out of __dev_xmit_skb()
and call it earlier. Then this pkt_len partial init is no longer needed.
Agreed, will change it for v2.
Thanks,
Daniel
