cc2236299f nl80211: Get all requested MLO links information from (re)association events
Currently only accepted MLO links information is getting parsed from
(re)association events. Add support to parse all the requested MLO links
information including rejected links. Get the rejected MLO links
information from netlink attributes if the kernel supports indicating
per link status. Otherwise get the rejected MLO links information by
parsing (Re)association Request and Response frame elements.

c2c4686228 Set NLA_F_NESTED flag with NL80211_ATTR_VENDOR_DATA conditionally
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.

6f19cc4d78 nl80211: Handle control port TX status events over nl80211
In order to retransmit faster in AP mode, hostapd can handle TX status
notifications. When using nl80211, this is currently only possible with
socket control messages. Add support for receiving such events directly
over nl80211 and detecting, if this feature is supported.

This finally allows for a clean separation between management/control
path (over nl80211) and in-kernel data path.

A follow up commit enables the feature in AP mode.

Control port TX status contains the original frame content for matching
with the current hostapd code. Furthermore, a cookie is included, which
allows for matching against outstanding cookies in the future. This
commit only prints the cookie value for debugging purposes on TX status
receive.
