In order to verify this, we will need to no, we don't set channels at probe time. We set the current_page/channel whatever the default is according to the hardware datasheet. I think this channel should be dropped and all drivers set the defaults before registering hw as what we do at e.g. at86rf230, see [0]. - Alex [0] https://elixir.bootlin.com/linux/v5.16/source/drivers/net/ieee802154/at86rf230.c#L1553
