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.

(see net/mac80211/main.c:ieee80211_init_cipher_suites). Allowing ciphers to be configurable is valuable for simulating older drivers that may not support all ciphers. This patch adds a new attribute: - HWSIM_ATTR_CIPHER_SUPPORT A u32 array/list of supported cipher types This only allows enabling/disabling cipher types listed in the (new) "hwsim_ciphers" array in mac80211_hwsim.c. Any unknown cipher type will result in -EINVAL.
