Azure NIC issues - possibly waagent related

Hi all,

I noticed recurring issues with the Azure CP R80.20 cluster and was wondering if anyone else had this behavior.

Basically the interfaces related to Azure Accelerated Networking unregister and may come up with a different name which breaks the traffic completely.

Although this was supposed to be solved by Jumbo HF take 17 it occurred again.

I believe it may be related to outdated buggy version of the Microsoft Azure Linux Agent (waagent) v2.2.11 installed on the VM (the last available version is v2.2.42)

Now waiting for my SR to be picked up...

Two other issues with the agent that are resolved in newer version:

-agent's logs filling up the Azure Serial Console making it unusable

-does not use the configured proxy server

Entries in /var/log/messages:

kernel: kernel: hv_netvsc 000d3a25-c27e-000d-3a25-c27e000d3a25 eth0: Data path switched from VF: enP1p0s2

kernel: kernel: hv_netvsc 000d3a25-c27e-000d-3a25-c27e000d3a25 eth0: VF unregistering: enP1p0s2
