Subject: [PATCH net v3 0/2] net: veth: ability to toggle GRO and XDP independently

It is rather confusing that GRO is automatically enabled, when an XDP program
is attached to a veth interface. Moreover, it is not possible to disable GRO
on a veth, if an XDP program is attached (which might be desirable in some use
cases).

Make GRO and XDP independent for a veth interface. udpgro_fwd

Changes in v3:
  * adjust udpgro_fwd selftest to explicitly enable GRO on veth interfaces,
    where it expects GRO to happen

Changes in v2:
  * add Fixes reference to commit description
  * fix commit message spelling

Ignat Korchagin (2):
  net: veth: do not manipulate GRO when using XDP
  selftests: net: veth: test the ability to independently manipulate GRO
    and XDP
