Since the MSI support is really your turf, I'll happily defer to
you on it. If you decide my patch should go in, I could add the
additional blacklisted bridges from your patch, add the tunable
to ignore the blacklist, and eliminate the distinction between
blacklisting MSI and MSI-X. Let me know whether I should go ahead
and commit that.
