Add IEEE 802.11 protocol(b/g/n/a/ac) Modes of APs

This patch appends the IEEE 802.11b/g/n/a/ac PHY
protocol modes of scanned Access Points
using internal logic.

Following logic is used to determine WLAN HW protocol:-
1) If “Supported rates” is only till 11 Mbps, and frequency is in
2.4GHz band, then protocol is 802.11B.
2) If “Supported rates” is till 54Mbps or “Extended supported rates”
are present, and frequency is in 2.4GHz band, then protocol is 802.11G.
3) If “Supported rates” is only till 54 Mbps, frequency is in 5GHz
band , then protocol is 802.11A.
4) If “HT capabilities” is supported , then protocol is 802.11N.
5) If “HT capabilities” & “VHT” is supported and frequency is in 5 GHz
band, then protocol is 802.11AC.
