ssid->frequency is one of the variables used to get the channel number from a given frequency. Leaving it as unchanged when pri/sec channel switch will cause picking up a wrong channel number after applying the secondary channel offset for HT40 and leads to failing interface bring-up.

|

|

* Example with problems:
|
|
* - 3 mesh nodes M1-M3, freq (5200, 5180)
|
|
* - other node O1, e.g. AP mode, freq (5180, 5200),
|
|
* Locations: O1 M1 M2 M3
|
|
*
|
|
* M3 can only send frames to M1 over M2, no direct connection is
|
|
* possible
|
|
* Start O1, M1 and M3 first, M1 or O1 will switch channels to align
|
|
* with* each other. M3 does not swap, because M1 or O1 cannot be
|
|
* reached. M2 is started afterwards and can either connect to M3 or M1
|
|
* because of this primary secondary channel switch.
|
|
*
|
|
* Solutions: (1) central coordination -> not always possible
|
|
* (2) disable pri/sec channel switch in mesh networks
|
|
*
|
|
* In AP mode, when all nodes can work independently, this poses of
|
|
* course no problem, therefore disable it only in mesh mode. */
