Yes, you are right but only in when DCB and RSS/TSS are off. When using DCB
and/or RSS/TSS you have some number TCs/TSS pools x 1 queue.
I am asking if configuring RX side and TX side in different mode is permitted
and make sense. From Niantic datasheet I did not seen any restrictions on this.
Some part of ixgbe pmd driver code make difference in that and some don't.
I need to unify this in one direction before enabling DCB in SR-IOV mode.
