I might have been mistaken.  Further testing makes me think the
pending-frames are properly dealt with.  I see them show back up
in the tx-complete logic about 30 second after the first chip reset logic hits.

That seems quite long to me, but then again, it appears that without a chip
reset, they never show back up in the tx-complete logic at all (and thus
the hang).

I'm testing now with just the pending-frames lockup check with a plain
chip reset as work-around (and no fiddling with pending-frames counter).

Thanks,
Ben
