* Your NIC's driver not yet being supported. [Here's](https://github.com/iovisor/bcc/blob/master/docs/kernel-versions.md#xdp) a NIC driver XDP support list. With enough Linux kernel development knowledge, you could try implementing XDP DRV support into your non-supported NIC's driver (I'd highly recommend giving [this](https://www.youtube.com/watch?v=ayFWnFj5fY8) video a watch!). * Your NIC's driver not yet being supported.

* You don't have enough RX/TX queues (e.g. not enabling multi-queue) or your RX/TX queue counts aren't matching. From the information I gathered, it's recommended to have one RX and TX queue per CPU core/thread. You could try learning how to use [ethtool](https://www.poftut.com/linux-ethtool-tutorial-usage-examples/) and try altering the NIC's RX/TX queue settings ([this](https://www.linode.com/docs/guides/multiqueue-nic/) article may be helpful!). * You don't have enough RX/TX queues (e.g. not enabling multi-queue) or your RX/TX queue counts aren't matching.
