I applied these three patches now to make progress with the pending NAN
patches, but I'm wondering whether it would make more sense to modify
the interface to higher layers to generate the cookie values within
wpa_supplicant instead of getting them from the higher layers. Isn't the
current design depending on the higher layers managing a pool of unique
cookie values? wpa_supplicant could do that and the control interface
command would simple get a parameter in for requesting TX status and the
response to that control interface command would return the assigned
cookie when that TX status was requested.
