I'm not sure if there's any specific way to do this unless the motherboard has a power sensor specifically for the Ethernet controller. Is the Ethernet integrated onto the motherboard, or is it a separate card? You might want to see if lm-sensors can help (Google for it). You might also want to try to get IPMI working if your board supports it, but most consumer level boards don't.

We need a few more details on your system (what type of motherboard you have). Why, exactly, do you need to do this?

AFAIK lm-sensors does not show power consumption figures.

Looking at 'Intel.com' for Ethernet 'Intel 82573L' specifications. You can get all the info you need.

The only way you could possibly tell is to run a system amp probe load test w/ disabled and then enabled. Or more to the point disabled and enabled with and with out various parameters.

Spec sheets can't include any system usage. Things like setting checksum offload could cause a big difference. The system processor could take quite a bit more power than the nic.

I doubt you can use any of the results to any useful end.

Hi,

You can get the typical settings. For a general user there should not be the need to know the load for a NIC. You would need a 'extender' that would be constructed with the means to check the current via a sense. Not every one would want to purchase a 'pci/pcie' extender to just measure the load. The specs do provide enough detail to setup a good idea as to what is used typically.
We're not threading a needle here!

If the OP needs the load then he/she should know how to measure and DAS the data for computation over a period. Then conclude a load for the NIC over the measured test.
