Scalable Functions

The scalable functions are supported starting from this release. Before using it in DPDK, the configuration should be done firstly.

To set up the Scalable Functions follow the instructions in this link: https://github.com/Mellanox/scalablefunctions/wiki/MLNX_OFED-step-by-step-guide

The section “SubFunction support” in the file “doc/guides/nics/mlx5.rst” can be used as the reference to use scalable functions in DPDK.

• To probe a SF (9 as the index in the example):

  Copy

  Copied!

              
  
              
  -a auxiliary:mlx5_core.sf.9
          

• To probe SF representors:

  Copy

  Copied!

              
  
              
  -a <PCI_BDF>,representor=sf[0-N]
          

• To probe SF representors in bonding mode:

  Copy

  Copied!

              
  
              
  -a <Primary_PCI_BDF>,representor=pf[0,1]sf[0-N]
          

SF and VF representors cannot be probed with one “-a” parameter, but they can be attached dynamically and separately.
