This issue is not that issue. It is separate issue and in fact
it is private problem of driver and its author, what is safe,
what is not safe.

F.e. I see no cathastrophe even if MII registers are accessed without
any protections. Diag utilities do this from user space. 8)8)

de4x5 is hopeless. I added nice comment in softnet to it.
Unfortunately it was lost. 8)

Andi, neither you nor me nor Alan nor anyone are able to audit
all this unnevessarily overcomplicated code. It was buggy, is buggy
and will be buggy. It is inavoidable, as soon as you have hundreds
of drivers.
