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?

Thanks.
