Comment 35 for bug 1234743

Steve wanted a 0-day SRU with this so that we can build new phone images with that included. The way the patch is done is that it doesn't change anything on !arm; this both avoids potentially breaking i386/amd64/powerpc, and also avoids penalizing those platforms with the unnecessary extra netlink filter code. I uploaded it to unapproved to avoid blocking on that upload. But please feel free to reject if you would like the patch done in a different way, or some regression comes up during testing with the attached binaries.
