I wonder if there is a HAT for the Raspberry Pi 3 with two or three ethernet ports so the RP can also function as an ethernet switch.

Likely not as the GPIO I/O is not fast enough to obtain usable I/O speed..

You could do it at 10Mbps 10-baseT with a couple of SPI ENC28J60s (the Raspberry will drive 5 SPI devices with no special hardware needed), but it will be astoundingly slow.

Your best bet would probably be to use multiple USB-to-Ethernet adapters. But you might then run into USB bandwidth limitations.
The Pi is the wrong tool for the job really.
