Hi All,

I read below doc, and have one question:

http://docs.openvswitch.org/en/latest/intro/install/dpdk/
dpdk-socket-mem
Comma separated list of memory to pre-allocate from hugepages on specific sockets.

Question:
   OVS+DPDK can let user to specify the needed memory using dpdk-socket-mem. But the question is that how to know how much memory is needed. Is there some algorithm on how to calculate the memory?Thanks.

Br,
Wang Zhike
