Looking at this again I wonder if it would be of value to have this as
NL80211_EXT_FEATURES_ATTR_LEN in nl80211.h so user-space can check the
nla_len() against it and detect API in-compatibility. Just can not use
DIV_ROUND_UP() in that case. What's your opinion?
Well, userspace must not check it since it should be compatible with new
kernels ... That was kinda my original point about not liking it in the
header to start with :)
Understood.
Thanks,
