[Impact]
Ubuntu VM in Azure has network performance issue when check by using netcat&nload
Normal bandwidth is 50MB/s ~ 100MB/s, but it's 0.3MB/s when dropping happens
[Fix]
Upstream development
0d158852a8089099a6959ae235b20f230871982f ("hv_netvsc: Clean up two unused variables")
It's affected over 3.19.0-28-generic (vivid)
With this commit, I confirmed that the problem has gone by the testing.
[Testcase]
This is only for Azure service.
Make 2 vms on North Europe, West Europe and run below test script
NE
while true; do netcat -l 8080 < /dev/zero; done;
nload -u M eth0 ( need nload pkg )
WE
for i in {1..1000}
do
timeout 30s nc NE_HOST 8080 > /dev/null
done
Network performance dropping can be seen frequently |

[Impact]
Ubuntu VMs between different location, especially North Europe and East Eruope in this case) in Azure have network performance issue.
It should be around 100MB/s speed between them. but it's around 0.3MB/s when dropping happens.
