It's been a little more than a year since this question was raised.
1. What is the status of test integration and production readiness for multi channel?
2. I don't see RSS support from Windows Server 2019 clients connected to Samba v4.10 with when I run the PowerShell Get-SmbMultichannelConnection command. I only see SMB multi channel performance improvements with dual NIC on different subnets as noted in this thread:
If this expected behavior? I have the following settings in my config:
server multi channel support = yes
aio read size = 1
aio write size = 1
interfaces = eth0;speed=25000000000,capability=RSS eth1;speed=25000000000,capability=RSS
