 If you're referring to my developer branch on CGRAN of the bbn_80211b
code, I do not believe the transmit code currently works with GNURadio
3.2. I have gotten the receive code working, and am working on a version
that talks to the USRP2, but I have not touched the transmit code at
all. It likely still needs to be converted to the new hier_block2 API.
