[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 <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
