several: make the phy reflect the packet modulation.
Use the data rate and channel to determine 11b vs. 11g vs. 11a for:
* Aruba Networks encapsulated remote mirroring;
* Prism headers;
* *Peek remote protocol;
* Network Instruments^W^WViavi Observer;
* *Peek classic format;
* Shomiti Surveyor.
Note why we *don't* need to do that for NetMon captures.
