http://perforce.freebsd.org/chv.cgi?CH=153962 Change 153962 by thompsa@thompsa_burger on 2008/12/02 18:06:24 If the parent up/down task was queued then sync with it before returning from the vap ioctl. This means that the parent interface _should_ be up before we return to userland, it does not depend on the parent init succeeding, just that it was run. This fixes wpa_supplicant with ndis as it fires passthrough OID ioctls as soon as the vap is up yet the parent may still be down.
