[PATCH net-next 0/8] net: sched: cls: add extack support

[Alexander Aring <aring@mojatatu.com>]

Hi,

this patch adds extack support for TC classifier subsystem. The first
patch fixes some code style issues for this patch series pointed out
by checkpatch. The other patches until the last one prepares extack
handling for the TC classifier subsystem and handle generic extack
errors.

The last patch is an example for u32 classifier to add extack support
inside the callbacks delete and change. There exists a init callback as
well, but most classifier implementation run a kalloc() once to allocate
something. Not necessary _yet_ to add extack support now.

I know there are patches around which makes changes to these files.
I will rebase my stuff on Jiri's patches if they get in before mine.

- Alex
