Subject: tests: Validate that AP doesn't reflect station frames
X-Git-Tag: hostap_2_8~725

tests: Validate that AP doesn't reflect station frames

Add a new test to check that the AP won't send frames to the client if
it tries to talk to itself.

Note that this fails until the relevant mac80211 patch is merged.
