Detailed Description

Test initial channel settings for AP and non-AP STAs when those are not necessarily identical.

This test verifies the channel width used by the non-AP STA is properly advertised to the AP STA, and that invalid combinations get rejected. It generates DL and UL traffic (limited to 1 packet for each direction) and checks that the number of received packets matches with the expectation.
