Re: Re: Ethernet controllers..
Hi John,
Thanks for the update, I`m currently using RTL8139 based cards but my project requires alot of performance from the network elements and eventually Gigabit Ethernet..
In this reguard I`ll have to look into Intel cards sooner or later, can anyone tell me why the Intel 82544 driver uses the function "udelay" alot - I`m concerned that the udelay is a hardware delay which will prevent threads (or other 82544 cards in the system) from running.
Jim

The easiest route is probably a D-Link DFE-530TX+ PCI card which uses
the RTL8139 part and can be found via Amazon in the UK.

The i82544 featured on the Intel Pro/1000 ethernet card which appears to
have been replaced by the Pro/1000 GT card:
http://www.intel.com/products/desktop/adapters/pro1000gt/pro1000gt-overview.htm
The newer card uses the i82541 part which may or may not be compatible.

The 88E1111 is an ethernet PHY (transceiver), not a controller.
I hope this helps.
