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.

Ok. I will evaluate and update.

# 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.
