Johannes Berg says: ==================== Here's just the fix for that ancient bug: * remove wext calling ndo_do_ioctl, since nobody needs that now and it makes the type change easier * use struct iwreq instead of struct ifreq almost everywhere in wireless extensions code * copy only struct iwreq from userspace in dev_ioctl for the wireless extensions, since it's smaller than struct ifreq ==================== Signed-off-by: David S.
