Hi All,

I'm fairly new to xdp, i'm trying to run the testpmd with af_xdp. I have
checked all the prerequisites for af_xdp.
I see testpmd exiting with the following error,
./testpmd -c 0x3 -n 4 --vdev net_af_xdp0,iface=tap0 -- -i
EAL: Detected 8 lcore(s)

Configuring Port 0 (socket 0)
*xdp_umem_configure(): Failed to create umemeth_rx_queue_setup(): Failed to

Fail to configure port 0 rx queues
EAL: Error - exiting with code: 1
  Cause: Start ports failed

Seems like xsk_umem__create() is failing, could this be a kernel issue?
Before going further i wanted to confirm that my setup is fine and that
there are no obvious mistakes, here is my setup details:
debian buster kvm machine
4.19.0-9-amd64 kernel
iface argument is a tap interface
dpdk-stable-19.11.2

Any insight is appreciated.
Thanks!
