at86rf230.c and derivatives avoid this problem by setting
phy->current_* in the *_channel function.
But I'd agree that it's nicer to do this in one place, not in
every d
On the MRF24J40, link-layer acknowledgment request and retry must be
turned on explicitly for each packet. Turn this on in the hardware based
on the FC_ACK_REQ bit being set in the packet.
Also, now that failure to receive an ACK will cause the hardware to report
failure of transmission, change t

it was not functional. It can send some of the RPL messages, but no code
logic is present to interpret them, etc.

Thinking of it, probing by trying request_irq has an unpleasant ring
to it. Perhaps a better way would be to leave this deci

Yes, RPL uses link-layer information (ETX). It uses it for both, OF0 and MRHOF
