I've only used stats once or twice, so I'm not really an expert. But
having looked at stats.c, I strongly suggest to also look at
stats_display_memp(). That's because these days much of memory
allocation in lwip is done from memory pools, and I believe
stats_display_memp() is for monitoring those.
To be honest, I don't know what avail and max mean. I hope somebody
else on this list provides clues.
