Ok thanks. To confirm this is an issue with the zero-copy mode, can you try to
create the af_xdp interface in copy mode by adding the 'no-zero-copy' keyword
in the create command, eg.
~# vppctl create int af_xdp host-if no-zero-copy

Hi, Ben.
I figured out the problem in my setup that on the ixgbe driver.
1. ixgbe 5.1.0 (which don't have XDP enabled yet) + VPP master (that have your

Thanks.
Thx, Xuekun

Hi Xuekun,
I suspect you are using a Linux kernel >= 5.9. There was an ABI change between
5.8 and 5.9, the issue is discussed here:

I'd recommend using a Linux kernel between 5.6 and 5.9 f
