[PATCH v5] Print ip and port associated with descriptor with -yy

[Zubin Mithra]

Hello all,

This is the latest patch for extended socket fd decoding. A few points :-

> +#else
> +# define SOCK_DIAG_BY_FAMILY 20
> +  struct sock_diag_req {

Unless I'm mistaken this header is present on all linux systems in
/usr/include even with the dev packages installed.

 inet_diag_req_v2 is not present on all Linux systems.
