       devlink dev help

       devlink dev eswitch set DEV [ mode { legacy | switchdev } ] [ inline-
               mode { none | link | network | transport } ] [ encap {
               disable | enable } ]

DESCRIPTION         top

   devlink dev show - display devlink device attributes
       DEV - specifies the devlink device to show.  If this argument is
       omitted all devices are listed.

           Format is:

   devlink dev eswitch show - display devlink device eswitch attributes
   devlink dev eswitch set - sets devlink device eswitch attributes
       mode { legacy | switchdev }
              Set eswitch mode

              legacy - Legacy SRIOV

              switchdev - SRIOV switchdev offloads

       inline-mode { none | link | network | transport }
              Some HWs need the VF driver to put part of the packet headers
              on the TX descriptor so the e-switch can do proper matching
              and steering.

              none - None

              link - L2 mode

              network - L3 mode

              transport - L4 mode

       encap { disable | enable }
              Set eswitch encapsulation support

              disable - Disable encapsulation support

              enable - Enable encapsulation support

   devlink dev reload - perform hot reload of the driver.
       DEV - Specifies the devlink device to reload.
