I mean, if we request a scan with some parameters, and the cached results were received with different parameters, and real scanning is impossible now for whatever reason, then return empty results and EAGAIN code. Anyway, we should have a policy for all drivers, so let's stick to that policy.
I've had a look at mac80211, since that seems to be a good indicator of policy (mlme.c). It caches BSSs in dev->ieee80211_ptr->local->sta_bss_list. It accumulates BSSs, and doesn't do anything to 'pick out' specific ssid results after a specific ssid scan is initiated, or clear the list before initiating the scan. Without a mac80211 (or any other) card to check, it seems that the orinoco behaviour introduced by this patch is consistent with mac80211.
