This implements a workaround to prevent CI failures on specific hardware using an Intel E810 network card. When UserLevelNetworking is set to True, tuned attempts to set the combined channel count equal to the reserved CPUs but fails with the following error: tuned.utils.commands: Executing 'ethtool -L ens2f0 combined 1' error: netlink error: Device or resource busy The error occurs because the ice driver: ens2f0: Cannot change channels when RDMA is active. This issue causes the tuned profile to degrade. As a temporary solution, by adding 'module_blacklist=irdma' to the kernel Args we will block RDMA, to avoid these errors.
