<note important>
+
Please note that Mellanox network interface cards cannot be switched to DPDK using the driverctl utility — their driver is installed in a different way. They also remain under operating system control, therefore the interfaces will still appear in the output of ip/ipconfig utilities.
+
If it is necessary to install a driver to support DPDK on Mellanox network cards, please [[en:dpi:techsupport_info|contact technical support]].
