Zigbee MAC

Hi,

I am using UCLA_Zigbee_Phy on RFX2400 boards and trying to transmit
IEEE802.15.4 Zigbee packets using the board.

I am also working on developing a MAC layer stack for the same. I kindly
request you to let me know whether anyone is working on it and also
could I use a code which is available as of now. Please share your
thoughts about how to go about the same.

Thanks and Regards,

Sivaram
