I could not find a hook in cfg.c which is meant for configuring negotiated
pairwise cipher into driver. You mean add_key() ?, which configures
the key after the association.

In that case, I might need to introduce one more entry in
enum ieee80211_key_alg called ALG_NONE. When we have a new
entry in enum, we might end up handling that in all the case
statements wherever this enum is used (quite a few places in
mac80211 and almost all the drivers) to
mute compilation warnings.
