ipv4: prepare net initialization for IP accounting
Some places, that deal with IP statistics already have where to get a struct net from, but use it directly, without declaring a separate variable on the stack. So, save this net on the stack for future IP_XXX_STATS macros. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
