netdev-afxdp: Add interrupt mode netdev class.
The patch adds a new netdev class 'afxdp-nonpmd' to enable afxdp
interrupt mode. This is similar to 'type=afxdp', except that the
is_pmd field is set to false. As a result, the packet processing
is handled by main thread, not pmd thread. This avoids burning
the CPU to always 100% when there is no traffic.
