Zigbee's light_stwitch example cannot use multi-channel.

Zigbee's light_stwitch example failed to initialize after configuring CONFIG_ZIGBEE_CHANNEL_SELECTION_MODE_MULTI=y

Hi, 

How many channels are active? Do you increase CONFIG_ZIGBEE_APP_CB_QUEUE_LENGTH? Please check the note in the Configurable transmission power section:

Thank you. These configurations are very helpful.

What are the appropriate ZB_CONFIG_SCHEDULER_Q_SIZE and ZB_CONFIG_IOBUF_POOL_SIZE configurations for this example?

I have set them for high traffic.

#define ZB_CONFIG_SCHEDULER_Q_SIZE 48

#define ZB_CONFIG_IOBUF_POOL_SIZE 48

Will this take up more memory?
