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". |
