mac80211_hwsim: allow configurable cipher types
The mac80211_hwsim driver does not specify supported cipher types, which in turn enables all ciphers to be supported in software. (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.
