Re: [PATCH] net: Call ip_hdrlen() when skbuff is not fragment

When skbuff is fragment, we exit immediately and leave ip_hdrlen() as
unused. And remove the unnecessary local variable fragment.

I don't think this is a useful optimization sorry, the common case
will be just as likely to be a fragment as not so it's arbitrary
whether we read this simple value or not.

I'm not applying this, sorry.
