prima: Support for NAT keep alive packets
qcacld-2.0 to pronto propagation
This is the host driver implementation to support sending
fixed NAT keep alive packets to WiFi Network.
1. WifiHal issues start send packet with ip_packet, ip_packet_len,
destination mac address and period. Host driver populates the data
and sends WMI message to firmware to configure the tx pattern.
2. WifiHal upon sending stop packet, host driver sends delete
tx pattern to the firmware.
Additional changes are done to pass the pattern bitmap to WDA.
