Now that functions in lib80211 handle "const struct lib80211_crypto_ops", some structure can be constified as well. Constifying these structures moves some data to a read-only section, so increase overall security. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> --- Compile tested only.
