Network devices using the AF_XDP PMD will trigger interrupts
on reception of packets. The new PMD argument 'queue_irq'
allows the user to specify a core on which to pin interrupts
for a given queue. Multiple queue_irq arguments can be specified.
For example:
--vdev=net_af_xdp1,iface=eth0,queue_c

Minor nit, how about using below format for readability and align with other
enum type definition in DPDK?
enum supported_driver {
I40E_

This only makes sense in this file. Should be static.
