From 14e0f59a88cc22ceeb36e26b89b70b22292d23de Mon Sep 17 00:00:00 2001 From: Ramasamy Kaliappan Date: Thu, 27 Mar 2025 10:43:18 +0530 Subject: [PATCH] wifi: mac80211: update ML STA with EML capabilities When an AP and Non-AP MLD operates in EMLSR mode, EML capabilities advertised during Association contains information such as EMLSR transition delay, padding delay and transition timeout values. Save the EML capabilities information that is received during station addition and capabilities update in ieee80211_sta so that drivers can use it for triggering EMLSR operation.
