Calculating number of HugeTLBs required

[Patrick Mahan <mahan@mahan.org>]

Morning,

This might be simple question, but it has my curiosity itching.

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
