You might try ethtool commands it will have an option to "test" and reset options. these options may or may not be the exact same code as the older mii-tool. It is also possible that not all of the possible options in mii-tool and/or ethtool are actually implemented in the driver, so one may work and another may not.
I have had luck getting the test to reset the nic on enterprise grade nic's, not sure if they work on the cheaper ones.
