[PATCH v2 1/3] 6G: Define FILS discovery frame elements

[Aloka Dixit]

This patch defines IEEE Std 802.11ai-2016 9.6.8.36 FILS discovery
frame elements (Figures 9-687b, 9-687c).
Changes include 6GHz specific changes defined in IEEE P802.11ax/D6.0
Table 9-386—PHY Index subfield and 26.17.2.3.2, AP behavior for fast
passive scanning.
