A frame that a packet socket consumes was given to pkt_input() and then
logged as "Dropped, Unknown type" because it is neither IP nor ARP. With
a PTP grandmaster on the network that is one warning for each frame, and
the log of RAM fills in seconds, so it hides the messages of the start of
the system.
Do not log the frames of the type of PTP or of IPv6 when packet sockets
are enabled, as the driver of the legacy STM32 does.
