I don't see why you must use msecs_to_jiffies(), why not just change
FEC_MII_TIMEOUT to 30000?

That's a one-line, easy to validate, change.

Whereas if you also change the units of the timeout I have to go
through the entire driver to audit your patch, making sure none of the
FEC_MII_TIMEOUT uses in the driver have been missed.

When you make multiple changes at once, it leads to more work for the
patch reviewer, please avoid this whenever possible.

Thanks.
