I finally figured it out.
FAUCET sets ofp_switch_config.miss_send_len = 0 when the switch connects.
We do this because we don't want any packets coming to the controller, if
there is no matching flow in a table. We program a priority 0, actions=drop
flow in all tables as well, to really hammer
I apologize, I dropped the ball. I'll go take another look at this. I had a
go at reproducing it (with just a single table) and failed - the packet in
is sent.
It's only not sent, when FAUCET has put other flows in other tables and the
problem priority 0 rule is in table 2. I have some work to do

Hello,
Hoping I'm missing something obvious!
I have a flow like this:
$ grep CONTROLLER sab-dump-flows.log
cookie=0x5adc15c0, duration=63.446s, table=3, n_packets=60, n_bytes=3436,
priority=0 actions=CONTROLLER:96
I can cause packets to match it, but no packets are output ot the
controller.
