    [SCTP]: Fix sctp_cookie alignment in the packet. · 9834a2bb
    Vlad Yasevich authored
    On 64 bit architectures, sctp_cookie sent as part of INIT-ACK is not
    aligned on a 64 bit boundry and thus causes unaligned access exceptions.
    
    The layout of the cookie prameter is this:
    |<----- Parameter Header --------------------|<--- Cookie DATA --------
    -----------------------------------------------------------------------
    | param type (16 bits) | param len (16 bits) | sig [32 bytes] | cookie..
    -----------------------------------------------------------------------
    
    The cookie data portion contains 64 bit values on 64 bit architechtures
    (timeval) that fall on a 32 bit alignment boundry when used as part of
    the on-wire format, but align correctly when used in internal
    structures.  This patch explicitely pads the on-wire format so that
    it is properly aligned.
