From 11a766ce915fc9f8663714eac6d59239388534ea Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 25 Oct 2010 12:51:55 -0700 Subject: net: Increase xmit RECURSION_LIMIT to 10. Three is definitely too low, and we know from reports that GRE tunnels stacked as deeply as 37 levels cause stack overflows, so pick some reasonable value between those two. Signed-off-by: David S.
