    [NET]: Replace skb_pull/skb_postpull_rcsum with skb_pull_rcsum · cbb042f9

    We're now starting to have quite a number of places that do skb_pull
    followed immediately by an skb_postpull_rcsum.  We can merge these two
    operations into one function with skb_pull_rcsum.  This makes sense
    since most pull operations on receive skb's need to update the
    I've decided to make this out-of-line since it is fairly big and the
    fast path where hardware checksums are enabled need to call
    csum_partial anyway.
    Since this is a brand new function we get to add an extra check on the
    len argument.  As it is most callers of skb_pull ignore its return
    value which essentially means that there is no check on the len
