Merge branch 'inet_csums_part2'

Tom Herbert says:

====================
net: Checksum offload changes - Part II

I am working on overhauling RX checksum offload. Goals of this effort
are:

- Specify what exactly it means when driver returns CHECKSUM_UNNECESSARY
- Preserve CHECKSUM_COMPLETE through encapsulation layers
- Don't do skb_checksum more than once per packet
- Unify GRO and non-GRO csum verification as much as possible
- Unify the checksum functions (checksum_init)
- Simply code

What is in this second patch set:

- Call common inet checksum validation functions in ICMP{4,6},
  GRE{4,6}, and IGMP.
- In UDP, verify checksum before handing off to encap_rcv.
- Remove custom UDP checksum validation code in L2TP.

Please review carefully and test if possible, mucking with basic
checksum functions is always a little precarious :-)
