  === Mellanox ConnectX-4 support 
  
  anchor:connectx_support[]
  
  Mellanox ConnectX-4 adapter family supports 100/56/40/25/10 Gb/s Ethernet speeds. 
  Its DPDK support is a bit different from Intel DPDK support, more information can be found link:http://dpdk.org/doc/guides/nics/mlx5.html[here].
  Intel NICs do not require additional kernel drivers (except for igb_uio which is already supported in most distributions). ConnectX-4 works on top of Infiniband API (verbs) and requires special kernel modules/user space libs. 
  This means that it is required to install OFED package to be able to work with this NIC.
