It's mesh mode. I'll give that a try tomorrow thanks. Marcus also
pointed out I should double check for multiple hop routes (the fours XOs
are side by side on a bench, but best to be safe.)

I could not infer from your e-mail whether you are testing
infrastructure or mesh mode. If the latter, ethtool -S msh0 will give
you some additional counters on dropped frames:
# ethtool -S msh0
