Please teach me how to do that?

struct inet_addr {
	union {
		u32	v4;
		u32	v6[4];
	};
};

ie. exactly what that code is using already.

And it's called called inetpeer_addr, we have it already, there is no
need to make something new.

Making this code use a structure with completely unnecessary and
unused members is pointless and a step backwards.
