[net-next,0/2] export SO_REUSEADDR and SO_REUSEPORT via sock_diag

Hi,

We've found it useful to have SO_REUSEADDR and SO_REUSEPORT
available to understand when apps cannot bind() to specific
ports. I think this would be nice to have available as part
of monitoring tools as well. I can add this to 'ss' if this
series is accepted.

Thanks,

-Jason
