IRQ numbering is a little messy on MIPS. And there were no IRQ
counters in AR71XX PCI code. Try this patch too:
http://people.freebsd.org/~gonzo/patches/ar71xx_pci_intrcnt.diff

You'll need the first one too. Also try running 
/usr/src/tools/tools/crypto tool for performance testing.

I don't have RS Pro setup at the  moment, so can't test it myself
right now :( But will do over weekend.
