Trying again with HC1 compression, I see other isses. The first

frame is received correctly, but the following frames have an incorrect
packet length and generate RX FIFO errors. Forcing the send size to
12 bytes of payload in apps/examples/udp (vs 96), eliminates this
problem and the broadcast works well.
There is probably another issue related to broadcast TX setup: If
we are sending to the multicast or broadcast address, should we
