Bug description:
An issue has been identified with the NETVSC driver on Azure VMs. This
issues has been fixed by four patches, which are available in the
mainline kernel.
The issues is the following:
Outgoing traffic is sent from the guest to the Azure host over multiple
parallel channels. The issue causes the traffic to be unevenly balanced across
the channels, which results in a physical CPU on the Azure host becoming
overloaded. In turn, the network traffic on the overloaded channel experiences
significantly higher latency. This higher latency is causing issues for
customers.
This issue is resolved by the following four mainline commits:
71f21959dd55 ("hv_netvsc: Fix offset usage in netvsc_send_table()")
171c1fd98df3 ("hv_netvsc: Fix send_table offset in case of a host bug")
c39ea5cba5a2 ("hv_netvsc: Fix tx_table init in rndis_set_subchannel()")
b0689faa8efc ("hv_netvsc: Fix unwanted rx_table reset")
These four commits have been submitted to upstream stable.
We would like to request these commits in Azure kernels for Xenial and
Bionic

The 5.3 azure kernel in proposed already has all the required commits
linux-azure (5.3.0-1019.20) - proposed
- hv_netvsc: Fix offset usage in netvsc_send_table()
- hv_netvsc: Fix send_table offset in case of a host bug
linux-azure (5.3.0-1014.15)
- hv_netvsc: Fix unwanted rx_table reset
linux-azure (5.3.0-1013.14)
- hv_netvsc: Fix tx_table init in rndis_set_subchannel()
We will move the bionic:linux-azure to 5.3, so there's no need to fix it
on 5.0.
