[PATCH net] virtio-net: add missing virtqueue kick when flushing packets

We tends to batch submitting packets during XDP_TX. This requires to kick virtqueue after a batch, we tried to do it through xdp_do_flush_map() which only makes sense for devmap not XDP_TX. So explicitly kick the virtqueue in this case. Reported-by: Kimitoshi Takahashi

[PATCH] virtio_balloon: add array of stat names

Jason Wang points out that it's vary hard for users to build an array of stat names. The naive thing is to use VIRTIO_BALLOON_S_NR but that breaks if we add more stats. Let's add an array of reasonably readable names. Fixes: 6c64fe7f2 ("virtio_balloon: export hugetlb page allocation counts") Cc:
