Hi all
just few lines to point that, in the actual implementation of 802.11s, the
death of a node cause a network crash.
All machines i have in my testbed freeze on any node shutdown, and there is
no way out..need to hard reboot.
My evaluation of 802.11s has been heavily biased by this bug. Though it is
projected to deal with dynamic nodes, seems that actual implementation
cannot address node failure during data transfers.
I did same tests months ago, with older kernel and older ath5k (April
releases) and the mesh worked flawlessy.
So it seems to me that this bug has been introduced with latest release of
ath5k/802.11s code.
But it is hard for me to find where is the bug.
If anyone has time and ideas to start debugging, i am here to help.

I also tried with 3 or 4 nodes forcing the multi-hop with mpath del/new
commands and performance are similar.
My problem now is to evaluate the performance when a node is turned off.
Unfortunately this event causes the freezing of iperf and of the system.
I hope you are luckier than me
