Author: avg Date: Fri May 29 07:38:57 2020 New Revision: 361619 URL: https://svnweb.freebsd.org/changeset/base/361619 Log: MFC r361364: net80211: post RTM_IFINFO notification after toggling IFF_DRV_RUNNING This is useful when a wireless driver is stopped or started in response to events like an RF Kill button press. Applications like wpa_supplicant depend on such events to have a correct view of interface state.
