[PATCH net-next 1/2] virtio-net: correctly update XDP_TX counters
Commit 5b8f3c8d30a6 ("virtio_net: Add XDP related stats") tries to
count TX XDP stats in virtnet_receive(). This will cause several
issues:
- virtnet_xdp_sq() was called without checking whether or not XDP is
set. This may cause out of bound access when there's no enough txq
for XDP.
- Stats were updated even if there's no XDP/XDP_TX.
Fixing this by reusing

[PATCH vhost v11 00/10] virtio core prepares for AF_XDP
## About DMA APIs
Now, virtio may can not work with DMA APIs when virtio features do not have
VIRTIO_F_ACCESS_PLATFORM.
1. I tried to let DMA APIs return phy address by virtio-device. But DMA APIs just
work with the "real" devices.
2. I tried to let xsk support callballs to get phy address from virtio-net
driver as the dma address. But the maintainers of xsk may want to use
