I did a quick scan through the documentation, but I did not see any good guidelines for determining the number of HugeTLB based on the number of PMDs and number of RX/TX queues. I'm am looking at three different platforms, one has 2 ports (ixgbe), one has 3 ports (1 e1000 and 2 i40es) and a third has 2 ports (1 e1000 and 1 Cavium liquidIO). I'm trying to come up with some means of defining the HugeTLB requirements other than trial and error. Thanks, Patrick
