Which MIPS CPU and bootloader is on the 5gxi?  Atheros system-on-a-chip?
I wish it had more ROM and RAM, and a different antenna.

In practice, hslsd uses too much CPU because we run it with so many
debugging messages turned on.  It is possible for the daemon to get into
a "livelock" condition, where it is too busy printing debug messages to
actually get work done.

In theory, hslsd will use less CPU than any other linkstate algorithm
running on a network of similar (large) size, both because of the
hazy-sightedness (fewer LSUs to process), and because my implementation
is a bit "lazy" about running shortest paths first.
