From 99e3a44bac37ff033af711ec2ee8e48b6fabcad3 Mon Sep 17 00:00:00 2001 From: James Prestwood Date: Wed, 17 Oct 2018 12:33:06 -0700 Subject: mac80211_hwsim: allow setting iftype support The mac80211_hwsim driver hard codes its supported interface types. For testing purposes it would be valuable to allow changing these supported types in order to simulate actual drivers than support a limited set of iftypes. A new attribute was added to allow this: - HWSIM_ATTR_IFTYPE_SUPPORT A u32 bit field of supported NL80211_IFTYPE_* bits This will only enable/disable iftypes that mac80211_hwsim already supports. In order to accomplish this, the ieee80211_iface_limit structure needed to be built dynamically to only include limit rules for iftypes that the user requested to enable.
