So not using XDP is a problem. I looked at previous versions of this
patch, and it is all DPDK. But DPDK is not in mainline, XDP is. In
order for this to be merged into mainline you need a mainline user of
it.
Maybe you should abandon mainline, and just get this driver merged
into the DPDK fork of Linux?
