The insanely high amount of TX_RETRY (13) on the first (nanostation)
network might have had something to do with it. The debloated device (a
wndr 5700) had TX_RETRY=4.
It remains puzzling.
I am doing a new build of openwrt for the nanostation net (incorporating
babel-1.1 - thx!) But ran into problems elsewhere in getting a build
done, so I'm a ways from being able to play with this comprehensibly.
And I'd like to expose TX_RETRY to userspace at some point.
And it would be cool to get more drivers - like the iwl-lagn - debloated.
