There are a few places where the RDMA CM code handles IPv6 by doing
struct sockaddr addr;
u8 pad[sizeof(struct sockaddr_in6) -
sizeof(struct sockaddr)];
This is fragile and ugly; handle this in a better way with just
struct sockaddr_storage addr;
[ Also roll in patch from Aleksey Senin <alekseys@voltaire.com> to
switch to struct sockaddr_storage and get rid of padding arrays in
struct rdma_addr. ]
