The Signed-off should be in chronological order, before reviews.

As suggested in previous patch, the title should be
	net: fix IPv4 checksum

I am doing above modifications while merging.

More advices about submitting patches:
	- use -v2, -v3, etc when sending new versions
	- add a changelog below the line ---
	- use --in-reply-to to keep all versions threaded
