I'm not sure what you mean with "wifi frames that are not WPA". If the
client does not reply to EAPOL-Key packets (i.e., WPA 4-Way Handshake),
it will be deauthenticated after a short timeout. No data frames are
allowed from STAs that have not completed configured authentication.
There are number of places in the driver code that do this filtering.
These are mainly in hostap_80211_rx.c. Search, e.g., for
"drop_unencrypted" and"authorized".
