The timing here couldn't be better. I have DEFPAs in all my Alphas,  
but I just threw the first one into a sparc64, and I had exactly this  
problem. And the patch you posted solves it without any apparently  
problems.

Is this fix an appropriate one for committing to the source tree? (I  
haven't looked into the details of what your fix does when avoiding  
calling bus_dmamem_map().) Have you submitted it via send-pr? It  
seems like this should be there so everyone with a DEFPA in their  
Sparc can use it.

I noticed that with the FDDI interfaces in my Alphas, and fixed it a  
couple years ago. My fix was modified, and sent off to the libpcap  
source tree, and should be in src/lib/libpcap/pcap-bpf.c rev 1.16  
(see bin/28531). But sure enough, it still doesn't work in -current.  
I'll look into that and see if I can figure out what's wrong. (Up  
'till now, I'd still been running with my local patch.)

Anyway, thanks for the pdq_ifsubr.c patch!
