NAK for two reasons.  First, module parameters are not desirable
because their individual to one driver and a global solution should be
found so that all networking device drivers can use the solution.  This
will keep the interface to change/setup/modify networking drivers
consistent for all drivers.

Second and more importantly, if your NIC is broken, fix it.  Do not try
and create a software workaround so that you can continue to use a
broken NIC.  There are methods/tools available to properly reprogram
the EEPROM on a NIC, which is the right solution for your issue.
