[yellowfin] hamachi - 2.4 kernel problems

[Keith Underwood]

Ok, try applying this patch:

--- hamachi.c.2.4.orig  Mon May 21 18:43:38 2001
+++ hamachi.c   Mon May 21 18:42:25 2001
@@ -1199,6 +1199,8 @@
                return 1;
        }

+       netif_stop_queue(dev);
+
        /* Caution: the write order is important here, set the field
           with the "ownership" bits last. */


I think that does it.  It's probably not optimal, but I don't have a box
to test it on right now.
