I noticed something similar when testing Jiri's virtio_net selftests
patchset [1].
drivers/net/virtio_net/config includes virtio options but the
test also needs at least CONFIG_NET_VRF=y which is part of net/config.
Whatever the answer to your question, all config files should be
coherent on this matter.

c2518da8e6b0 selftests: bonding: Change script interpreter (v6.8-rc1)
