wifi: nl80211: add support to configure 6 GHz non-HT duplicate transmission
As per IEEE Std 802.11-2024, subclause 26.17.2.2, a 6 GHz AP can transmit
a Beacon frame using a non-HT duplicate PPDU, so that stations scanning
only PSC channels can discover it. Currently, there is no mechanism
to request the driver to transmit non-HT duplicate Beacon frames.
In [1], changes were made to parse the Beacon from user-space to set
the non-HT duplicate flag in the kernel. However, it was suggested that
non-HT transmission be part of the Beacon TX rate settings. Hence, add
NL80211_TXRATE_6GHZ_NON_HT_DUP as a flag attribute under
NL80211_ATTR_TX_RATES to let user-space request the driver to transmit
non-HT duplicate Beacons.
Also add validation to reject the Beacon if non-HT duplicate Beacon
transmission is enabled when legacy rates are not configured.
