ipv4: reset rt_iif for recirculated mcast/bcast out pkts
 
Multicast or broadcast egress packets have rt_iif set to the oif. These
packets might be recirculated back as input and lookup to the raw
sockets may fail because they are bound to the incoming interface
(skb_iif). If rt_iif is not zero, during the lookup, inet_iif() function
returns rt_iif instead of skb_iif. Hence, the lookup fails.

v2: Make it non vrf specific (David Ahern). Reword the changelog to
    reflect it.

	---help---
	The "Communication CPU to Application CPU Interface" (CAIF) is a packet
	based connection-oriented MUX protocol developed by ST-Ericsson for use
	with its modems. It is accessed from user space as sockets (PF_CAIF).

	Say Y (or M) here if you build for a phone product (e.g. Android or
	MeeGo ) that uses CAIF as transport, if unsure say N.

	If you select to build it as module then CAIF_NETDEV also needs to be
	built as modules. You will also need to say yes to any CAIF physical
	devices that your platform requires.

	See Documentation/networking/caif for a further explanation on how to
	use and configure CAIF.

config  CAIF_DEBUG
	bool "Enable Debug"
	depends on CAIF
	default n
	---help---
	Enable the inclusion of debug code in the CAIF stack.
	Be aware that doing this will impact performance.
	If unsure say N.

config CAIF_NETDEV
	tristate "CAIF GPRS Network device"
	depends on CAIF
	default CAIF
	---help---
	Say Y if you will be using a CAIF based GPRS network device.
	This can be either built-in or a loadable module,
	If you select to build it as a built-in then the main CAIF device must
	also be a built-in.
	If unsure say Y.

config CAIF_USB
	tristate "CAIF USB support"
	depends on CAIF
	default n
	---help---
	Say Y if you are using CAIF over USB CDC NCM.
	This can be either built-in or a loadable module,
	If you select to build it as a built-in then the main CAIF device must
	also be a built-in.
	If unsure say N.
