Subject: tests: Change vlan_id back and forth
X-Git-Tag: hostap_2_5~792
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=bbe9eddce0f48d443f0d2321df40bbbb9447c2a9;p=thirdparty%2Fhostap.git

tests: Change vlan_id back and forth

Enhance test ap_vlan_wpa2_radius_id_change to change the VLAN-ID
back as a last step. This ensures that the wpa_group for VLAN-ID 1
did not enter FATAL_FAILURE state during the test.
