Subject: tests: Verify that changing p2p_disabled removes/adds P2P device
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f64452e723f216ce5987a5256e992138124f1b5c;p=thirdparty%2Fhostap.git

tests: Verify that changing p2p_disabled removes/adds P2P device

Add a test to verify that if p2p_disabled is changed on the (possible)
parent device for a dedicated P2P device, then the dedicated P2P device
is added or removed as appropriate.
