just a nit, maybe reorder the fields to better cope with their IPv6 
buddies (where  there is
such) from sockaddr_in6?

Also I see that both IPv6 header and IB GRH have a traffic class field 
which is skipped in both
cases for the related sockaddr_ structure, not sure why, is this 
something the kernel stack decides on and uses but not available for 
applications to read/modify?

struct sockaddr_in6 {
         unsigned short int      sin6_family;    /* AF_INET6 */
         __be16                  sin6_port;      /* Transport layer port 
# */
         __be32                  sin6_flowinfo;  /* IPv6 flow information */
         struct in6_addr         sin6_addr;      /* IPv6 address */
         __u32                   sin6_scope_id;  /* scope id (new in 
RFC2553) */
};
