driver: Add a packet filtering function declaration
Add a new function declaration that will allow wpa_supplicant to request
the driver to configure data frame filters for specific cases.
Add definitions that will allow frame filtering for stations as
required by Hotspot 2.0:
1. Gratuitous ARP
2. Unsolicited NA
3. Unicast IP packets encrypted with GTK
