the linkwatch code can overflow on a jiffies wrap, scheduling
work with a too large delay. If the delay is 0x8000,
internal_add_timer() seems to overflow too, hiding the bug, so
this isn't triggered too easily.
I had tested the patch under linux system, maybe this mail is correct.
Fix error point to options in ip_options_fragment(). optptr get a error
pointer to the ipv4 header, correct is pointer to ipv4 options.
