I do agree you and Saeed that instead of port function param, port function

resource is more suitable here even though its bool.

I believe flexibility can be achieved with some FW message? Parav can you
investigate ? To be clear here the knob must be specific to sw_steering
exposed as memory resource.

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

this looks like an abuse of the interface, I literally meant to control the
amount of ICM pages dedicated for SW steering per function, this requires
some FW support, but i think this is the correct direction.

# 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.
