pub fn admit(packet: &ReceivedPacketRef<'_>)Expand description
Decide whether an arriving packet is a Node Management Request this device will act on, and queue it if so.
Registered as a receive handler at bring-up; returns false always,
so the packet still reaches every other observer. Everything refused
is refused silently — an unlisted sender learns nothing about whether
the device is manageable, not even that it declined to say.
