Which place did you mean? I have just performed an updated and I
couldn't find any /tos/lib/mac folder.

I think that the right way to proceed is for

The Porto's zigbee that you are speaking about is the one available in
the /tos/lib/net/zigbee folder?

But I think that the standard compliant IEEE 802.15.4 MAC

Where is the IEEE 802.15.4 MAC located?
