So at this point it's completely a driver problem.  If you're actually
connected, then *both* these commands should report that fact.  NM
trusts the kernel here, and the kernel is letting us down.  NM has no
way of knowing that we're connected to anything at all if the kernel
doesn't report that correctly :(
