  By the way, Komali just reported another bug internally where
instantiating an SR-IOV Virtual Function causes cxgb4vf to be automatically
loaded, which is normal behavior.  But then when she attempts to unload
cxgb4vf, it simply gets reloaded again.  This is with:

The patch you provided last Wednesday _does_ solve this new problem, but
doesn't solve the problem that she originally reported.  Let me know if
you'd like to see the udevadm output for 4.15-rc4 prior to applying your
patch.
