wifi: cfg80211: Add support to get EMLSR capabilities of non-AP MLD
The Enhanced multi-link single-radio (EMLSR) operation allows a non-AP MLD
with multiple receive chains to listen on one or more EMLSR links when the
corresponding non-AP STA(s) affiliated with the non-AP MLD is (are) in
the awake state. [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.
