Configuring multiple Ethernet controllers (including commercial ones, once they were available) with one CPU board created a router.
This means you should be able use the original 16-bit software on these members of the PCnet family of single-chip Ethernet controllers.
Amiga 2065 the first Ethernet controller for Amiga computer family.
Motherboards with an embedded Ethernet controller which supports Wake-on-LAN do not need a cable.
Optional hardware included a high-speed FDDI interface and a second Ethernet controller.
The Nvidia-built Ethernet controller was supposedly capable of reducing CPU overhead while being also very fast.
For example, many Ethernet controllers implement interrupt "rate limiting", which causes the controller to wait a programmable minimum amount of time between each interrupt it generates.
For example, an Ethernet controller with interrupt rate limiting will buffer the packets it receives from the network in between each interrupt.
Other peripheral boards such as an Ethernet controller were purchased from other OEMs.
Note that the newly announced Ethernet controller works with VT-d, and it also contains some nice features of its own.
