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.
