[wireless-next,v14,0/4] wifi: cfg80211/mac80211: Set/get wiphy parameters on per-radio basis

Currently wiphy level configurations like RTS threshold, lacks radio
level get/set support and same value is applied to all radios of wiphy.
Add support to parse radio id attribute and use the same to apply the
configuration to corresponding radio of a multi radio wiphy.

This design will not disturb the global wiphy configuration. If radio id
is not passed from userspace, then the existing design of setting
attribute to all the radios will hold good.

Also add support to get the radio specific attributes in a multi-radio
wiphy from userspace.

The attributes that can be handled for each radio are:
NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX
NL80211_ATTR_WIPHY_ANTENNA_RX
NL80211_ATTR_WIPHY_RETRY_SHORT
NL80211_ATTR_WIPHY_RETRY_LONG
NL80211_ATTR_WIPHY_FRAG_THRESHOLD
NL80211_ATTR_WIPHY_RTS_THRESHOLD
NL80211_ATTR_WIPHY_COVERAGE_CLASS
NL80211_ATTR_TXQ_LIMIT
NL80211_ATTR_TXQ_MEMORY_LIMIT
NL80211_ATTR_TXQ_QUANTUM

With this design, the new userspace designed to set/get per-radio
parameters can work with both traditional and multi-radio wiphys.

v14:
 - Fixed errors and warnings reported by kernel test bot.
v13:
 - Fixed errors and warnings reported by kernel test bot.
v12:
 - Added a patch to introduce a new NL attribute -
   NL80211_ATTR_WIPHY_RADIO_INDEX.
 - Modified the APIs handling per-radio attributes to take radio index
   from the userspace.
v11:
 - Resolved warning flagged by clang compiler.
v10:
 - Modified data type of radio_id to int.
 - Resolved memory leak.
v9:
 - Fixed errors reported by patchwork's wifibot.
v8:
 - Fixed warning reported by kernel test bot regarding variable
   initialization.
v7:
 - Addressed cosmetic comments from Johannes Berg.
 - Removed patches - wifi: cfg80211: set tx power per radio in a wiphy
   and wifi: mac80211: set tx power per radio in a wiphy.
v6:
 - Fixed warning reported by kernel test bot.
v5:
 - Changed default value of radio id from 0xff to -1.
 - Changed driver callback order for global wiphy parameters.
 - Fixed other minor comments related to code-cleanup.
v4:
 - Fixed stack frame size warning.
 - Added S-O-B tag in patches 4/5 and 5/5.
v3:
 - Fixed warnings to refresh copyright, to curb long lines of code and
   to include kernel documentation for a few variables.
v2:
 - Converted the series to [PATCH] from [PATCH RFC], link to which is,
   https://patchwork.kernel.org/project/linux-wireless/cover/20250107182506.1838704-1-quic_ramess@quicinc.com/
