From 6bffd1fe06db7000b43d417344bcc6690d909cf1 Mon Sep 17 00:00:00 2001 From: Srikanth Marepalli Date: Fri, 23 Oct 2020 02:36:07 +0530 Subject: cfg80211: Enhance the AKM advertizement to support per interface Commit ab4dfa20534e ("cfg80211: Allow drivers to advertise supported AKM suites") introduces the support to advertize supported AKMs to userspace. This needs an enhancement to advertize the AKM support per interface type, specifically for the cfg80211-based drivers that implement SME and use different mechanisms to support the AKM's for each interface type (e.g., the support for SAE, OWE AKM's take different paths for such drivers on STA/AP mode). This commit aims the same and enhances the earlier mechanism of advertizing the AKMs per wiphy. Add new nl80211 attributes and data structure to provide supported AKMs per interface type to userspace. The AKMs advertized in akm_suites are default capabilities if not advertized for a specific interface type in iftype_akm_suites.
