WCH's cheap Ethernet microcontrollers: An overview

WCH now offers a bunch of 32-bit RISC-V microcontrollers with built-in Ethernet.

Note that there are two different types of Ethernet support in these microcontrollers:

• The standard Ethernet type has a 10 MBit/s MAC & PHY and does not support 100Mbit/s or 1Gbit/s
• The advanced Ethernet controllers support 1 Gbit/s MAC (meaning they support 1 Gbit/s Ethernet with external PHY) and have a built-in 10 Mbit/s PHY (i.e. without external PHY they only support 10 Mbit/s)
