From 8cdfab8a43bb4b3da686ea503a702cb6f9f6a803 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Fri, 6 Jan 2006 23:04:01 -0800 Subject: [IPV4]: reset IPCB flags when neccessary Reset IPSKB_XFRM_TUNNEL_SIZE flags in ipip and ip_gre hard_start_xmit function before the packet reenters IP. This is neccessary so the encapsulated packets are checked not to be oversized in xfrm4_output.c again. Reset all flags in sit when a packet changes its address family. Also remove some obsolete IPSKB flags. Signed-off-by: Patrick McHardy Signed-off-by: David S.
