The unmodified tulip driver checks both MWI and cacheline-size because

Maybe the generic pci_set_mwi() can verify cacheline size is non-zero?
I don't think each driver should need to enforce this.
Agreed.
If the arches do not behave consistently, we need to keep the check in
the tulip driver, to avoid incorrectly programming the csr0 MWI bit.
Why not fix the arches to be consistent?
There's alot more drivers than arches...and we have control
of the arch specific PCI support.
Agreed.
