Leann,

This patch fixes the noise injected into the kernel log for servers that 
have multi-receive queue adapters. I'd like to see this applied soon 
(and uploaded) since I'm not sure what action upstream is taking on 
this. I can't seem to get any traction there. As soon as I see what 
they're gonna do I'll send a correction.
