On my QNAP setup, its running Samba Version 4.13.14 and has multichannel enabled with "server multi channel support = yes" in the smb.conf file.
I'm trying to disable RSS for the various interfaces and am currently using the entry of:
interfaces = "eth0;capability=RDMA" "eth2;capability=RDMA" "eth4;capability=RDMA"
This will disable the RSS flag in the IOCTL FSCTL_QUERY_NETWORK_INTERFACE_INFO
I find there is no way in that interfaces line to just turn off RSS for that interface.
This line should work:
interfaces = "eth0;capability=" "eth2;capability=" "eth4;capability="
but the packet traces show that RSS is still on.
Do we need something like
interfaces = "eth0;capability=NO_RSS" "eth2;capability=NO_RSS" "eth4;capability=NO_RSS"
Or just fix the case of "capability="
