Wireshark uses WinPcap [1] to interface with networking devices on
Windows, so support for these devices will have to be added there
first (this will likely involve adding a new linktype to the official
list [2]).

Once that is done we can add a dissector to Wireshark for the framing
protocol, but that will be (mostly) useless without the WinPcap
component already in place.

(For reference, a general spec seems to be available at [3].)

Cheers,
Evan
