The module parameter eeprom=  accepts a list of filenames (looked for
in /lib/firmware) to fake eeprom images. The list is in probe order,
which means it is unpredictable if you have more than one spec card
plugged -- but it's the same every time your reload the module.

This is a tool for developers who want to experiment with eeproms, so
this "rude" approach to multi-card setups is not considered an issue.

When using the SPEC as White Rabbit grandmaster, you need to feed it
with 10MHz, which would kill the computer with an interrupt flood.

DIO interrupts are now disabled if they consume more than 80% of the
total time, which usually triggers between 100kHz and 200kHz. Network
interrupts are not affected.

Thanks to Anders Wallin for reporting the problem and helping in the
diagnosis.

We haven't been able to run Message Signalled Interrupt
reliably, for a quirck in the Gennum chip and the kernel
insisting to configure it according to the standard. So this
adds "use_msi" as a module parameter, disabled by default.
See documentation for details.
