Merge branch 'flowi6_tos'

Daniel Borkmann says:

====================
flowi6_tos fixes

This set is a follow-up to address Jiri's recent feedback [1] on
the flowi6_tos issue, that it is not used for IPv6 route lookups.
The three patches fix all current users of flowi6_tos and remove
the define to avoid any future confusion on this. Tested the vxlan
and geneve ones with IPv6 routing rules. For details, please see
individual patches.

[ As fixes are currently applied against net-next tree, I've rebased
  it against that. ]

Thanks!
