    wext: allow returning NULL stats · df2b35b6
    Johannes Berg authored
    Currently, wext drivers cannot return NULL for stats even though
    that would make the ioctl return -EOPNOTSUPP because that would
    mean they are no longer listed in /proc/net/wireless. This patch
    changes the wext core's behaviour to list them if they have any
    wireless_handlers, but only show their stats when available, so
    that drivers can start returning NULL if stats are currently not
    available, reducing confusion for e.g. IBSS.
