This patch series has 2 patches. Patch 1/2: keep vnet header zeroed if XDP is loaded for small buffer With this fix, we do not need to care about vnet header in XDP meta data support for small buffer, even though XDP meta data uses in front of packet as same as vnet header. It would be best if this patch goes into stable. This patch is based on the feedback by Jason Wang and Michael S. Tsirkin. https://lore.kernel.org/netdev/9a0a1469-c8a7-8223-a4d5-dad656a142fc@xxxxxxxxxx/ https://lore.kernel.org/netdev/20200223031314-mutt-send-email-mst@xxxxxxxxxx/ Patch 2/2: add XDP meta data support Thanks to Jason Wang, Daniel Borkmann and Michael S.
