[PATCH 15/16] tests: Add a WNM tests to check candidate list is used if not required

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Benjamin Berg <benjamin.berg@xxxxxxxxx>

This tests that the candidate list is used even if it is not required
because the abridged and preferred candidate list included bits are not
set.
