Well, the first one is only needed for PMKSA caching which is an
optional feature and as such, the driver would not need to support it.
However, the error value looks a bit odd (EOPNOTSUPP would be more
reasonable for that case). Likewise, "Network is unreachable" for
SIOCSIWAP is a bit odd error code since wpa_supplicant was just trying
to clean any possibly configured BSSID filtering with 00:00:00:00:00:00
(since ap_scan=2 was used here). I would agree that there is probably
need for some minor cleanup in the driver. Anyway, I would assume that
neither of these are actually causing any noticeable problems apart from
these debug messages.
