What makes you think it isn't enabled? Do you see interrupt activity on all queues?

@stephenw10 I dont know how to verify whether the rss was enabled :(

As far as I know there is nothing to set for igb NICs. If the kernel has RSS support (which it does) then it will be used.

The answer for the question: dmesg| grep -i queue

[23.05-RELEASE][root@GW.Tel]/root: dmesg| grep -i queue
igb0: Using 2 RX queues 2 TX queues
igb0: netmap queues/slots: TX 2/1024, RX 2/1024
igb1: Using 2 RX queues 2 TX queues
igb1: netmap queues/slots: TX 2/1024, RX 2/1024
ada0: Command Queueing enabled

I would try vmstat -i and make sure you see interrupts on both queues on each NIC when it's passing traffic.
