[PATCH wpan/next v3 4/9] net: mac802154: Don't limit the FILTER_NONE level to monitors

[Miquel Raynal <miquel.raynal@bootlin.com>]

Historically, only monitors were using promiscuous mode and this
promiscuous mode was not the one from the spec but actually implied no
filtering at all (sniffers). Now that we have a more fine grained
approach, we can ensure all interfaces which would be expecting no
filter at all could get it without being a monitor interface.

Having this in place will allow us to clarify the additional software
checks compared to the hardware capabilities.
