Detailed Description

Test the exchange of EML Operating Mode Notification frames.

This test considers an AP MLD and a non-AP MLD with EMLSR activated. Upon association, the non-AP MLD sends an EML Operating Mode Notification frame, which is however corrupted by using a post reception error model (installed on the AP MLD). We keep corrupting the EML Notification frames transmitted by the non-AP MLD until the frame is dropped due to exceeded max retry limit. It is checked that:

the Association Request contains a Multi-Link Element including an EML Capabilities field that contains the expected values for Padding Delay and Transition Delay
the Association Response contains a Multi-Link Element including an EML Capabilities field that contains the expected value for Transition Timeout
all EML Notification frames contain the expected values for EMLSR Mode, EMLMR Mode and Link Bitmap fields and are transmitted on the link used for association
the correct EMLSR link set is stored by the EMLSR Manager, both when the transition timeout expires and when an EML Notification response is received from the AP MLD (thus, the correct EMLSR link set is stored after whichever of the two events occur first)
