From 34cc7ba6398203aab4056917fa1e2aa5988487aa Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Sat, 23 Feb 2008 20:19:20 -0800 Subject: [IP_TUNNEL]: Don't limit the number of tunnels with generic name explicitly. Use the added dev_alloc_name() call to create tunnel device name, rather than iterate in a hand-made loop with an artificial limit. Thanks Patrick for noticing this. [ The way this works is, when the device is actually registered, the generic code noticed the '%' in the name and invokes dev_alloc_name() to fully resolve the name. -DaveM ] Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
