Ok wow... it's interesting what you might see when you stare at a screen 
and observe over time... so, I am in fact seeing BLQ work following a 
reboot, but, look how long it takes.  ~9.5 minutes following reboot 
command.  This is absolutely reproducible and happens every time the 
ACX5048 reboots, I did it about 5 times. I'd like to see this happen 
immediately following network convergence, ... like right around the 
time interfaces come up and routing protocol(s) converge... ospf full 
state, bgp established, etc.

Times hacks for what I observed...

00:00 - reboot
02:00 - acx5048 console login prompt
04:10 - ospf full, pinging loopback
09:38 - dhcpv6 blq tcp session seen (and wiresharked)
