I will post those commits once I see them go through.

These items are needed for the 14.04.5 and 16.04.1 HWE kernels, and 16.10, (and by extension, 16.04.2 HWE).

Joshua R. Poulson (jrp) wrote on 2016-12-22:

After performance testing, it looks like we need this upstream commit:
"Drivers: hv: vmbus: Base host signaling strictly on the ring state" http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=74198eb4a42c4a3c4fbef08fa01a291a282f7c2e

Also, we need to add the file for SR-IOV interface bonding:
"tools: hv: Add a script to help bonding synthetic and VF NICs" http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=178cd55f086629cf0bad9c66c793a7e2bcc3abb6

Can we get these two? We did some testing by adding the script manually so we're sure that will work, and our upstream linux-next testing has the other commit and we're getting the performance we're expecting.

Hi Tim,

We've verified the 2 updated test kernels hv.2 from comment #7 and network performance is back to the maximum throughput.
Also, the bond script is present and functional.
Thank you!
