> When ovs dpdk is run with dpdk compatible drivers, its socket mem is set
to (64MB + 512MB) per socket, otherwise only 64MB
(for eg using dpdk virt devices) as far as the current tests require.
Testpmd app would need around ~338 MB (n_mbuf=155456, mbuf_size=2176) in
its mempool, we would need in total:
64 MB (+ 512 MB) + 338 MB. I just rounded up the requirement for testpmd to
448 MB so that, we either configure 512 MB
or 1GB in hugepage per socket.
Thanks.
