Add helper function generic_mii_ioctl to MII lib, use it in 8139cp net drvr

TODO, in rough priority order:
* Test Tx checksumming thoroughly
* dev->tx_timeout
* Support forcing media type with a module parameter,
like dl2k.c/sundance.c
* Constants (module parms?) for Rx work limit
* Complete reset on PciErr
* Consider Rx interrupt mitigation using TimerIntr
