Hi, All
I used VPP21.01 and AF_XDP on a physical nic.
I followed the guide in https://docs.fd.io/vpp/21.01/d8/d44/af_xdp_doc.html that
1. ip link set dev <iface> promisc on
2. vppctl create int af_xdp host-if ... // load the default one,
which I think should forward all received packets from kernel to VPP
3. vppctl set int mac address <iface> <mac> // set to the NIC MAC.
4. vppctl set int ip addr ...
However "vppctl ping" still failed with "l3 mac mismatch".
vpp# show errors

20 ip4-glean ARP requests sent

However in VPP, "trace add af_xdp-input 10", and "show trace"
Packet 1
00:14:16:539735: af_xdp-input
af_xdp: enp9s0f0/0 (2) next-node ethernet-input

00:14:16:539748: error-punt
rx:enp9s0f0/0
00:14:16:539750: punt

Does anyone have any ideas?
Many thanks.
Thx, Xuekun
