I've built the latest (2.16.4) version of ixgbevf on Ubuntu 15.04. I have an 
issue where only the first (rx-0) of two receive queues is being used. While 
attempting to debug this, I noticed that I was unable to view or change RSS 
settings:

# ethtool --show-rxfh-indir eth0
Cannot get RX ring count: Operation not supported

I see that patch https://patchwork.ozlabs.org/patch/497193/ was accepted, but 
those changes don't seem to be present in the 2.16.4 source? I'm very 
unfamiliar with the kernel driver ecosystem, so these may be malformed 
questions, but:

a) Why are these changes in the kernel source tree but not in ixgbevf source 
tree?
b) What's the best way to integrate these changes myself, and will this break 
anything?
c) Are there any other relevant changes missing from 2.16.4?

Thanks,
Aris
