[IEEE 802.11be-2024, (35.3.17 Enhanced multi-link single-radio (EMLSR) operation)] An MLD which intends to enable EMLSR operations will set the EML Capabilities Present subfield to 1 and shall set the EMLSR Support subfield in the Common Info field of the Basic Multi-Link element to 1 in all Management frames that include the Basic Multi-Link element except Authentication frames. EML capabilities contains information such as EML Transition timeout, Padding delay and Transition delay. These fields needs to updated to drivers to trigger EMLSR operation and to transmit and receive initial control frame and data frames. Add support to receive EML Capabilities subfield that non-AP MLD advertises during (re)association request and send it to underlying drivers during ADD/SET station.
