+
+prandom_u32() previously was only calling get_random_u32() so it's been
+dropped with Linux 6.1.0. So let's directly call get_random_u32() if Linux
+version >= 6.1.0.

+
+Starting from Linux 5.19 stop_ap() requires unsigned int link_id as
+parameter. Then from Linux 6.1 on lot of other cfg80211 APIs require
+int link_id to deal with MLO, so let's add that parameter too.

+Subject: [PATCH] Fix struct station_parameters Linux 6.1 build failure
+
+Starting from Linux 6.1 struct station_parameters has changed by moving
+some member to its child struct link_station_parameters. Let's extract the
+values of the needed members into local values at the beginning of
+functions and substitute the member access with the local variables.
