P2P usage in the 6 GHz band is not standardized yet by WFA. Disable P2P
operations in the 6 GHz band to avoid potential interop issues with
existing P2P devices in production. P2P operations in the 6 GHz band can
be reenabled later after defining standard ways to address potential
interop issues with existing P2P devices.

Previously, the configuration to disable the 6 GHz band remained local
to the P2P interface. With this there is a possibility of 6 GHz channels
being included in the channel list when the channel list needs to be
updated if the state changes on one of the interfaces.
Include the configuration to disable the 6 GHz band for P2P as a global
configuration value to prevent the inclusion of 6 GHz channels in the
channel list for P2P when the channel list needs to be updated during
the state change in one of the interfaces.

The newer kernel versions enforce strict netlink attribute policy
validation and will cause cfg80211 to reject vendor commands with
NL80211_ATTR_VENDOR_DATA if NLA_F_NESTED attribute is not set but
if the vendor command is expecting nested data within
NL80211_ATTR_VENDOR_DATA attribute.
Most of the earlier instances were addressed by adding NLA_F_NESTED
flag in nla_nest_start(). This commit addresses the remaining
instance in which NL80211_ATTR_VENDOR_DATA is populated using data
set by user through the control interface.
Enhance the control interface VENDOR command to indicate whether the
vendor subcommand uses nested attributes within NL80211_ATTR_VENDOR_DATA
attribute or not.
Set NLA_F_NESTED flag for existing QCA vendor commands which use nested
attributes within the NL80211_ATTR_VENDOR_DATA attributes so that the
old frameworks implementations for already existing commands work
without any issues.
