Packets with Failed CRCs are being Acked #11
Description
Correct me if I'm wrong, but after a quick perusal of the driver I can't find anywhere where it checks if the CRC was correct. This means that packets are being acked that fail the CRC. This causes problems in higher layers.
In cc2420x, a failed crc packet never makes it out of DriverLayerP and therefore can't be acked in SoftwareAckLayer.
I ran into this when the first packet in a series of blip fragments wasn't received successfully, but the second one was causing BLIP to try to write to an unallocated buffer.
