Sure.
I currently think of user interface something like below,
I will get back with more plumbing of netlink and enum/string.

# to enable
devlink port function resource set pci/0000:03:00.0/port_index device_memory/sw_steering 1

# to disable 
devlink port function resource set pci/0000:03:00.0/port_index device_memory/sw_steering 0 (current default)

Thanks Jakub, Saeed for the inputs and direction.
