From: Akihiko Odaki <akihiko.odaki@daynix.com>

VIRTIO_NET_F_RSC_EXT is implemented in the rx data path, which vhost
implements, so vhost needs to support the feature if it is ever to be
enabled with vhost. The feature must be disabled otherwise.

Fixes: 2974e916df87 ("virtio-net: support RSC v4/v6 tcp traffic for Windows HCK")
