kernel: add vhost-net module
vhost-net is used to accelerate traffic to virtualisation guests that use the virtio-net network card in QEMU. Generally it is invoked by specifying "vhost=on" to a QEMU -netdev device: qemu-system-aarch64 -nographic -M virt -cpu host \ --enable-kvm -bios u-boot.bin -smp 1 -m 2048 \ -drive file=openwrt-armsr-armv8.img,format=raw,index=0,media=disk \ -device "virtio-net,netdev=landev,disable-legacy=off,disable-modern=off" \ -netdev "tap,id=landev,helper=/usr/lib/qemu-bridge-helper --br=br-lan,vhost=on" Signed-off-by: Mathew McBride <matt@traverse.com.au> (cherry picked from commit d188db8aed74547f98b905254d4f57baf225f1d6)
