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.
