Dear NetDevs

This series removes an abuse of VLAN CFI bit in Linux networking stack.
Currently Linux always clears the bit on outgoing traffic and presents
it cleared to userspace (even via AF_PACKET/tcpdump when hw-accelerated).

This uses a new vlan_present bit in struct skbuff, and removes an assumption
that vlan_proto != 0 when VLAN tag is present.

As I can't test most of the driver changes, please look at them carefully.

The series is supposed to be bisect-friendly and that requires temporary
insertion of #define VLAN_TAG_PRESENT in BPF code to be able to split
JIT changes per architecture.

v2: rebase onto net-next

This patch series is really way too large.

You're going to have to find a way to combine related changes, or submit
this as a series of logical sets, one at a time.

The dependency graph is really sparse: main patch 25 depends on all previous,
19-23 all depend only on 18 and 26 depends on 25.

That's it. So the question is: how would it be easier for you to manage?

Ah, I forgot about patches 1-2 that most depend on... So if you get those two
early, then most others can be split.

Best Regards,
Michał Mirosław
