Subject: [PATCH v11 11/22] wifi: nxpwifi: implement cfg80211 ops for STA and AP modes
Date: Wed, 29 Apr 2026 03:40:10 +0800 [thread overview]
Message-ID: <20260428194021.785252-12-jeff.chen_1@nxp.com> (raw)
In-Reply-To: <20260428194021.785252-1-jeff.chen_1@nxp.com>
Implement the required cfg80211_ops callbacks to support both station and
AP modes using the NXP firmware interface.
Because the firmware handles association through a dedicated command
sequence, the driver cannot rely on mac80211 for authentication or
association. Provide separate handling to support SAE-based authentication
for wpa_supplicant and hostapd, along with firmware-driven association
management.
