DLT for Radiotap+WiMAX?

["Charles Clancy" <clancy () cs umd edu>]

I need a metadata header for WiMAX common-part sublayer.  I see that
802.16 CPS has a DLT already allocated, which is a good start.

It seemed logical to extend the Radiotap header with some WiMAX-specific
fields, and reuse much of the existing infrastructure, however the
Radiotap header has no way of specifying the type of packet it's
encapsulating.  To solve this conundrum, there are a few options:

1. Allocate another DLT specifically for Radiotap+WiMAX

2. Extend the Radiotap header to indicate what protocol it's encapsulating

3. Don't use Radiotap, and develop something else

What's the group's thoughts on these options, and which would be most
preferred?  #1 seems easiest, and #2 seems most logical.
