Thanks, Sangjin. This is exactly i’m looking for. Sorry, I should’ve googled it first. It’s good to know that hash key of repetitive 0x6d5a still yields good load balancing results.

I'm wondering if there is a configuration or mechanism to get a symmetric hash so that all packets for a given flow will be in the same queue. Thanks in advance.
