Subject[PATCH net-next 0/2] XDP transmission for tuntap
Date
Hi all:

This series tries to implement XDP transmission (ndo_xdp_xmit) for
tuntap. Pointer ring was used for queuing both XDP buffers and
sk_buff, this is done by encoding the type into lowest bit of the
pointer and storin XDP metadata in the headroom of XDP buff.

Tests gets 3.05 Mpps when doing xdp_redirect_map from ixgbe to VM
(testpmd + virtio-net in guest).

Please review.

Thanks

Jason Wang (2):
tun/tap: use ptr_ring instead of skb_array
tuntap: XDP transmission
