Thomas I assumed that the 802.11s switching solution would switch the packet through the path with the best signal strength since that path would have the highest transmit rate and the least bit error rate. I used 'iw dev wlan1 mpath dujmp' to get the switching routes and A remained routing directly to C even though C was 2 miles away and B was about a half mile from A.
So the 'iw dev wlan1 station dump' command will show the tx and rx bit rate of the last transmission rather than the negotiated bit rate of the current link budget...
