If there are undesired side effects from
wpas_select_network_from_last_scan(), those need to be fixed for
Interworking case anyway, so yes, I'd like to see a single mechanism to
be used and any possible issues with it getting resolved. These two
cases are pretty much identical in the sense that both of them may have
run through a scan recently and could re-use information from it. The
Interworking one is guaranteed to have run through a scan, but these can
be handled with the same implementation with the use of that time limit.
The actual time limit value could end up becoming a configurable
parameter in the future, but a hard-coded limit would be fine as an
initial step.
