[wireless-next,v6,0/5] wifi: cfg80211/mac80211: Set/get wiphy parameters on per-radio basis

Message

Currently wiphy level configurations like RTS threshold, TX power etc.
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_FREQ
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_WIPHY_DYN_AC

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

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/[e-mail]/
