Hub or switching chips?

I’m developing to hardware connection with RJ45 to RJ45 like hub.
Can I do this to use W5200 /5300 or the other tcp/ip chips?
If it’s not, could you suggest hub or switching chips?
Thanks advance

All WIZnet Chips are for end-device.
WIZnet have no chips for switch as HUB.

Refer to Realteck web site.

Thank you.
