[PATCH 0/2] [NET]: RFC-compliant UDP-Lite support (RFC 3828)

[PATCH 0/2] [NET]: RFC-compliant UDP-Lite support (RFC 3828)

[Gerrit Renker]

[UDP] This is a finalised, polished and tidied up revision of the full UDP-Lite patch. 
      It features:
	* RFC 3828 - compliant support for UDP-Lite over IPv4 and IPv6
	* consolidated and shared generic code between UDP and UDP-Lite
          (thanks to the help of Dave Miller)
	* separation of files specific to UDP-Lite
	* MIB/statistics support in /proc/net/snmp{6} and /proc/net/udplite{6}
	* basic netfilter/xfrm support
	* API documentation in Documentation/networking/udplite.txt

C h a n g e l o g
-----------------
Although no negative feedback has been received from IPv6-developers, the integration of UDP-Litev6
has been overhauled, in particular to make the protocol initialisation in af_inet6.c consistent with
the existing code. The detailed changes:

        * added IPV6_ADDRFORM support for UDP-Lite
	* updated documentation with regard to most recent changes
        * rewrote the UDP-Lite initialisation in af_inet6.c from scratch - it is now fully
          consistent with the existing coding style
	* fixed typos
        * made the error handling in udpv6_queue_rcv_skb consistent: to return `-1' on error
          (it used to return 0 when either skb_checksum_complete or sock_queue_rcv_skb failed)

Apart from this, the v6-side technically is not much different from the v4-side, which has been
under revision/discussion as an RFC patch for a while. The code has been thoroughly tested.


If there are no further objections or code comments, I propose this for inclusion in 2.6.20.
