Okay, that explains it. So I can have a Tested-by: ... I just grep for NETDEV_PRE_UP in compat-wireless and it is only in include/net/compat-2.6.31.h (not in 2.6.30) and I am on 2.6.30.5-X . I can grab the rawhide 2.6.31 rpms and try it quickly; and possibly look at some ugly quick hack backport that? Stay tuned. Thanks for the help.
