Hi Steffen,

Like we discussed on v9 of this series, I do prefer to see this code
merged before merge window. It will simplify so much for me, like
UAPI exposure for iproute2 and *swan* forks. The internal API for
our mlx5 refactoring e.t.c.

The code in our regression is all time and it is completely safe for any
non-packet offload devices.

Thanks
