selftests: net: veth: test own ndo-xmit after peer GRO toggle while down
Test that a veth device advertises ndo-xmit when GRO is enabled on its
peer while both are down and only the device is brought up.
Commit 7a6102aa6df0 ("veth: Update XDP feature set when bringing up
device") made veth_open() set the flag in this case, and selftests were
requested in its review [1].
The block now ends with GRO enabled while the peer is down, so the
aggregation check that follows covers NAPI enabled by veth_open() again.
Commit c017800af5c7 ("selftests: net: veth: test peer ndo-xmit after GRO
toggle while down") had moved it to veth_set_features() [2].
