And what the heck happens if every single device driver tries to
handle this problem in the same way?  It makes no sense to make
the user specify N special module parameters just to get a working
system using MSI-X.

This must be fixed in a centralized way that allows coordination
between devices which compete for MSI-X vector resources, rather than
in a way that is specific to each and every device type.

I am not applying this patch, sorry.
