The thing is, Gnu Radio is largely about the *PHY* layer in the protocol stack (I say "largely" because it takes excursions into non-PHY territory from time to time). The key point is that Gnu Radio *isn't* about packet-decoding and related machinery, but rather about *signal processing*. Granted, the "end game" of that signal processing often ends up in packetized bits, but Gnu Radio isn't about the semantic "meaning" of those bits--it's up to other bits and pieces to make sense of that. For example, if you implemented an 802.11 "stack", you'd (on the receive side) inject the demodulated (and framed) bits into a virtual network interface in your operating system, which would treat them like any other bits arriving from a network interface.
