- * This is a simplest example of multi-interface and multi-channel 802.11s mesh network
- *
- * Every mesh station has 2 interfaces configured on two different channels:
- *
- * channel: i j
- * | |
- * station: [ STA ]
- *
- * Chain topology is created:
- *
- * 1 2 2 3 3 1
- * | | | | | |
- * [STA 1] <-- 120 m --> [STA 2] <-- 120 m --> [STA 3]
- * 10.0.0.1 10.0.0.2 10.0.0.3
- *
- * Then STA1 ping STA3

- * Parameters tuning and assertions are omitted for clarity.
