Hi Charles,
Thank you for the patch! Perhaps something to improve:

vlan_changelink silently ignores attempts to change the vlan id
or protocol id of an existing vlan interface. Implement by adding
the new vlan id and protocol to the interface's vlan group and then
removing the old vlan id and protocol from the vlan group.

IPVS setups with local client and remote tunnel server need
to create exception for the local virtual IP. What we do is to
change PMTU from 64KB (on "lo") to 1460 in the common case.

Thanks, David!
Unless there is something fundamentally broken, there is no

This allows further redirection of xdp_frames like

The intermediate XDP, redirecting packets from NIC to the other veth,
reuses xdp_mem_info from NIC so that page recycling of the NIC works on

From: Toshiaki Makita
All oversized packets including GSO packets are dropped if XDP is
enabled on receiver side, so don't send such packets from peer.
Drop TSO and SCTP fragmentation features so that veth devices themselves
segment packets with XDP enabled. Also cap MTU accordingly.

Move XDP and napi related fields in veth_priv to newly created veth_rq
structure.
When xdp_frames are enqueued from ndo_xdp_xmit and XDP_TX, rxq is
selected by current cpu.
When skbs are enqueued from the peer device, rxq is determined by its
peer's txq. In this way we can

We need some mechanism to disable napi_direct on calling
xdp_return_frame_rx_napi() from some context.
When veth gets support of XDP_REDIRECT, it will redirects packets which
are redirected from other devices. On redirection veth will reuse
xdp_mem_info of the redirection so
From: Toshiaki Makita
This allows NIC's XDP to redirect packets to veth. The destination veth
device enqueues redirected packets to the napi ring of its peer, then
they are processed by XDP on its peer veth device.
This can be thought as calling another XDP program by XDP program using
REDIRECT,
From: Toshiaki Makita
This is basic implementation of veth driver XDP.
Incoming packets are sent from the peer veth device in the form of skb,
so this is generally doing the same thing as generic XDP.
This itself is not so useful, but a starting point to implement other
useful veth XDP features
From: Toshiaki Makita
This is preparation for XDP TX and ndo_xdp_xmit.
Add another napi ring and handle redirected xdp_frames through it.
v2:
- Use another ring instead of using flag to differentiate skb and
xdp_frame. This approach makes bulk skb transmit possible in
veth_xmit later.

Aquire txq lock instead of rxq ptr_ring lock so we avoid per-packet
lock when skb->xmit_more is true. We ensure that rxqs are always not
less than txqs and txq to rxq is one to one mapping, so we can
completely remove rxq side lock.
Since we removed rxq side lock, this chan
From: Toshiaki Makita
This patch set introduces driver XDP for veth.
Basically this is used in conjunction with redirect action of another XDP
program.
NIC ---> veth===veth
(XDP) (redirect)(XDP)
In this case xdp_frame can be forwarded to the peer veth without
modification, so
