Subject: [PATCH net-next 0/6] net: sched: sch: introduce extack support

Hi,

this patch series basically add support for extack in common qdisc handling.
Additional it adds extack pointer to common qdisc callback handling this
offers per qdisc implementation to setting the extack message for each
failure over netlink.

The extack message will be set deeper in qdisc functions but going not
deeper as net core api. For qdisc module callback handling, the extack
will not be set. This will be part of per qdisc extack handling.

I also want to prepare patches to handle extack per qdisc module...
so there will come a lot of more patches, just cut them down to make
it reviewable.

There are some above 80-chars width warnings, which I ignore because
it looks more ugly otherwise.

This patch-series based on patches by David Ahren which gave me some
hints how to deal with extack support.
