Why generic is a better name? When you have "x86_64-default-linuxapp-icc", this feels like this is default configuration for given architecture among others, which will give best performance (what native suggests) If I would know nothing about DPDK and see available configs first time, I would pick this one, because this is default one J. "generic" stress more that this config supports generic features of different machine types. But this is how I feel, as I said I would prefer "generic", but I can survive with existing one.
