To be able to run DPDK on Intel cards, it is required to change the default
Intel driver to either `vfio-pci` or `igb_uio` driver. The process is
described in `DPDK manual page regarding Linux drivers
<https://doc.dpdk.org/guides/linux_gsg/linux_drivers.html>`_.
<https://doc.dpdk.org/guides/linux_gsg/linux_drivers.html>`_.
The Intel NICs have the amount of RX/TX descriptors capped at 4096.
This should be possible to change by manually compiling the DPDK while
changing the value of respective macros for the desired drivers
(e.g. IXGBE_MAX_RING_DESC/I40E_MAX_RING_DESC).
DPDK is natively supported by Mellanox and thus their NICs should work
"out of the box".
