From f8e09b973ae8489b88394bff0118d19f989bf277 Mon Sep 17 00:00:00 2001 From: Akihiko Odaki Date: Fri, 2 Aug 2024 14:38:19 +0900 Subject: [PATCH] vhost: Add VIRTIO_NET_F_RSC_EXT to vhost feature bits 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.
