Detailed Description

This test verifies that communication between an AP and a STA resumes after that both switch channel and PHY band.

The channel switch is scheduled to happen during the transmission of a frame sent by the STA to the AP. AP discards the frame, STA associates with the AP again and the AP finally receives the frame successfully.
