[mc1322x] Fragmented packets: could not allocate a queuebuf

[Daniel Berenguer]

Following my tests about sending fragmented UDP packets...

Receiving multiple data packets of 512 bytes seems to cause the
following Contiki run-time error:
queuebuf_new_from_packetbuf: could not allocate a queuebuf

The first receptions work just fine - hence my initial happiness :-) -
but later transmissions end by encountering the above error. I've
tested with smaller packets and I'm not able to reproduce the problem.
Maybe 1300 bytes is too much for a single packet ??

I'm now trying to know whether this problem could be due to some kind
of "time" overlap between incoming packets...

Daniel.
