Maybe I don't understand the question well, because it doesn't seem really different of what other PMDs do. Assuming your NIC is PCI, you can access it via uio (igb_uio) or VFIO. > Perhaps this is more of a hugetlbfs question than DPDK but I thought I'd > start here. It's a pleasure to receive new drivers.
