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). This gives us ~20% improvments
compared to use skb during redirect.
Please review.
Changes from V1:
- slient warnings
- fix typos
- add skb mode number in the commit log
Series applied, thanks Jason.
There was some overlap with recent changes from Jesper, please take
a look.
Thank you.
The changes looks good, will have a test and report.
Thanks
