No, since they do pretty different things.

Not sure what you mean.  If we put msi-x info under /sys, then you can
figure out which interrupts belong to a given HCA by following the
device link from /sys/class/infiniband.  Similarly if /proc/interrupts
gives the PCI device, then you have the same ability.  So either way
works as far as I can tell.
