I've chatted with someone about it, and they seemed to think it's
suspicious, but I'm not going to push it further until I have modem showing
that it's in DOCSIS 3.1 for upstream.

I do need to see if I can sort out what the SB8200's status messages are:

CM-STATUS message sent. Event Type Code: 24; Chan ID: 48; DSID: N/A; MAC
Addr: N/A; OFDM/OFDMA Profile ID: 2

That's definitely an option for me, as I don't have to worry about a 2Gbps
total traffic, only about 1.03Gbps (since cable is so asymmetric).

But I'm also not sure I want to go with another ARM box.  The small x64
boxes are looking like a much better long-term option.
