[issue1774] New IP header cleanup branch available for testing

[Matthew Dillon]

    I have re-merged master into my iphdr branch on leaf.  It could use
    some testing again.

    I haven't found anything that would explain the corruption Peter
    originally reported in this bug#, is it possible that it might have
    been a kernel misbuild?

    In anycase, the branch is synchronized with head now and I would like
    to have another go at testing.
