Subject: [PATCH v4 1/1] wifi: nl80211: Extend del pmksa support for SAE and OWE security
Date: Wed, 29 Nov 2023 18:20:43 +0530
Message-Id: <ecdae726459e0944c377a6a6f6cb2c34d2e057d0.1701262123.git.vinayak.yadawad@broadcom.com>

Current handling of del pmksa with SSID is limited to FILS
security. In the current change the del pmksa support is extended
to SAE/OWE security offloads as well. For OWE/SAE offloads, the
PMK is generated and cached at driver/FW, so user app needs the
capability to request cache deletion based on SSID for drivers
supporting SAE/OWE offload.
