            Bug ID: 100081
           Summary: sll_family required for bind() on AF_PACKET socket
           Product: Documentation
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: man-pages
          Assignee: documentation_man-pages-ztI5WcYan/vQLgFONoPN62D2FQJk+8+b@public.gmane.org
          Reporter: a0vhv-zqRNUXuvxA0b1SvskN2V4Q@public.gmane.org
        Regression: No

This is from "man 7 packet":
>When you send packets it is enough to specify sll_family, sll_addr, sll_halen, sll_ifindex.  The other fields should be 0. sll_hatype and sll_pkttype are set on received packets for your information. For bind only sll_protocol and sll_ifindex are used.

However, the last sentence is not correct. You have to specifiy sll_family for
bind() too, otherwise it will fail.

--- Comment #1 from Michael Kerrisk <mtk.manpages-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> ---
By chance, this was actually reported and fixed a few weeks ago, and the text
that will appear in the next man-pages release is:

       Fields used for binding are sll_family (should be
       AF_PACKET), sll_protocol, and sll_ifindex.
