Hi Jakub & Paolo,

I would like to send the v2 series but now it depends on two bugfix patches
that were submitted to 'net' as

https://lore.kernel.org/netdev/3c4e8106-83d0-4c1c-a3bd-8d9343d2d557@xxxxxxxxxx/T/#m0caa2ce66da8213c8594bce7d0ff55baeafeee05

Without them the v2 is not applicable to net-next...

Can I include these 2 patches into v2 so they will be present on both net and
net-next? Or how to proceed in this situations?

Thanks,
Ivan
