Hi! ethtool has a new option --set-rxfh-indir that should allow one to modify the RSS indirection table. This would allow to tune the number of queues to match the number of processors. For example, actually, it is not possible to load-balance 8 IRQ on 3 CPU. With the possibility to modify the indirection table, we could limit the number of queues to 3 without using options.
This option is supported by bnx2x and cxgb4. For 8257X cards, from the spec, it is possible to modify RETA while the interface is up. Currently, the indirection table is setup in igb_setup_mrqc(). Is the implementation of --set-rxfh-indir planned for igb?
