UART to ETHERNET module with support for 802.1x

[Rigolon]

Hey guys,

I'm looking for a module to convert UART to ETHERNET for a project. But it needs to support IEEE 802.1x.
I've found the XPORT EDGE from LANTRONIX, but it's about US$50.
I've used before the USR-TCP232-T2 from USRIOT, which was about US$12, but it doesn't support 802.1x.

Does anyone know any alternatives?

Thx in advance
