Here you go.

commit 45b503548210fe6f23e92b856421c2a3f05fd034
Author: Laszlo Attila Toth <panther@...abit.hu>
Date:   Tue Feb 12 22:42:09 2008 -0800

    [RTNETLINK]: Send a single notification on device state changes.

contains the following gem:

        if (tb[IFLA_LINKMODE]) {
-               write_lock_bh(&dev_base_lock);
-               dev->link_mode = nla_get_u8(tb[IFLA_LINKMODE]);
-               write_unlock_bh(&dev_base_lock);
+               if (dev->link_mode != nla_get_u8(tb[IFLA_LINKMODE])) {
+                       write_lock_bh(&dev_base_lock);
+                       dev->link_mode = nla_get_u8(tb[IFLA_LINKMODE]);
+                       write_lock_bh(&dev_base_lock);
+                       modified = 1;
+               }
        }

and even with that fixed it breaks NetworkManager (on my test box it apparently
can't get the IP address using DHCP).  Reverting this commit makes things
work again.

Well, it looks like this patch went to you untested and unreviewed, so may I
gently request that it be reverted from your tree, pretty please?

Thanks,
Rafael
