    ipv6: add new struct ipcm6_cookie · 26879da5
    Wei Wang authored
    In the sendmsg function of UDP, raw, ICMP and l2tp sockets, we use local
    variables like hlimits, tclass, opt and dontfrag and pass them to corresponding
    functions like ip6_make_skb, ip6_append_data and xxx_push_pending_frames.
    This is not a good practice and makes it hard to add new parameters.
    This fix introduces a new struct ipcm6_cookie similar to ipcm_cookie in
    ipv4 and include the above mentioned variables. And we only pass the
    pointer to this structure to corresponding functions. This makes it easier
    to add new parameters in the future and makes the function cleaner.
