> The netlink_diag can be built as a module, just like it's done in

> 
> The core dumping message carries the basic info about netlink sockets:
> family, type and protocol, portis, dst_group, dst_portid, state.
> 
> Groups can be received as an optional parameter NETLINK_DIAG_GROUPS.
> 
> Netlink sockets cab be filtered by protocols.
> 
> The socket inode number and cookie is reserved for future per-socket info
> retrieving. The per-protocol filtering is also reserved for future by
> requiring the sdiag_protocol to be zero.
> 
> The file /proc/net/netlink doesn't provide enough information for
> dumping netlink sockets. It doesn't provide dst_group, dst_portid,
> groups above 32.
> 
> v2: fix NETLINK_DIAG_MAX. Now it's equal to the last constant.
