I dump the packet in at86rf230_xmit and
at86rf230_rx_read_frame_complete (just before
ieee802154_rx_irqsafe(lp->hw, skb, lqi)). This is wireshark analyse of
the two packets. The first one is correct and comes from the sender,
the second is from the receiver (I manually created the hex dump file)
which is wrong! So something seem to occur when the frame goes to the
transceiver.
Those dump was created with :
root@OpenWrt:/#ieee802154_rx_irqsafe(lp->hw, skb, lqi);
