Got it, it's what I figured.

Agree.   A short-term version would be a cross-platform object you
could instantiate with an interface name to create and you'd get two
gr.msg_queue's, one each for rx and tx packet data.  It really calls
for either an mblock (which exists), or the message passing extension
to gr-blocks that we've been tossing around.
