Implement TX and RX path handling for NAN Data Path (NDP) frames, enabling data communication between NAN peers during scheduled availability windows. TX path: - Select TX channel based on current time slot: use DW channel during Discovery Windows, or FAW channel from local schedule during Further Availability Windows. - Verify peer availability before transmission by checking committed DW schedule or FAW of the peer schedule. RX path: - Extend NAN receive filtering to handle NAN_DATA interface frames. - Accept incoming frames during FAW slots when channel matches local schedule.
