>Description:
        The netstat(1) ignores option "-L" (dont show link-level routes).
        The code handling option L is removed when cleaning up of
        OSI network stack removal.

>How-To-Repeat:
        run "netstat -nrL"

>Fix:
        Re-add RTF_LLINFO handling to show.c.
        or run "netstat -nrL | grep -v L"
