How can I calculate the necessary resources for NATMAP? I am talk about next resources: dev.netmap.buf_num dev.netmap.ring_num dev.netmap.ring_size dev.netmap.if_num dev.netmap.if_size For example for case of ix0 6+6 rings, 2048+2048 slots, 20 additional pipes igb0 6+6 rings, 1024+1024 slots, 4 additional pipes open 6 netmap's to ix0, 1+1 rings each open 6 netmap's to igb0, 1+1 rings each open 20 pipes over ix0 open 4 pipes over igb0 What's total number of resources I am planed to use?
