Support for RTL837x based 2.5Gb managed switches

Hardware Questions and Recommendations
1

Hi all,

For home use, I need a cheap and small 2.5GbE managed switch with 4 (max. 5) 2.5Gb ports, where I can configure VLANs and connect to my main router via 2.5Gbps link, something like:

The most interesting option for me is the TP-Link TL-SE2106, but I would be fine with any no-name brand as long as it might potentially be supported by OpenWrt firmware and has a small size (not a 8+ ports version).

So, is there OpenWrt support for any 2.5Gb managed switch on Realtek RTL837x with a small number of ports and non-PoE?

Thank you.

:slightly_smiling_face: Tried.
There, the 2.5Gb ports are only available on the large-sized Zyxel XGS1250-12 with the RTL9302B.
Actually, I wasn't able to find any information about OpenWrt support for the RTL837x in the OpenWrt forum. I found only this information:

RTL837x series
Lightweight managed, or unmanaged switch chips.):

  • RTL8370 series
  • These chips have the following features:
    • 8051 CPU core
    • 8-port Gigabit switch with embedded PHYs
    • Since the software has an 8051 CPU, they are not useful for running Linux.
    • The 8051 core can be disabled for running in unmanaged mode.

If not, then you are out of luck. Note I actually own a XGS1250. Current support is rather basic at best.

rtl8372/rtl8373 isn't going to happen with openwrt. From my google search I think it's an 8051 micro controller core?

I don't have a datasheet to confirm, but the block diagram I found features hooking up an application processor to the 10G port and talking to it over mdio/i2c?
