From f6d2e5abf154da59ccb3bcac23438f2230c8948a Mon Sep 17 00:00:00 2001 From: Benjamin Berg Date: Wed, 1 Jan 2025 07:05:35 +0200 Subject: wifi: nl80211: permit userspace to pass supported selectors Currently the SAE_H2E selector already exists, which needs to be implemented by the SME. As new such selectors might be added in the future, add a feature to permit userspace to report a selector as supported. If not given, the kernel should assume that userspace does support SAE_H2E.
