Hi,
I have a simple setup in one machine and use userplane OVS-2.7 with
DPDK-16.11.1.
27afd0dc-cdac-4bb4-947c-65e13df66e99
Bridge "br0"
Controller "tcp:10.1.2.2"
is_connected: true
fail_mode: secure
Port "dpdkr2"
Interface "dpdkr2"
type: dpdkr
Port "dpdkr1"
Interface "dpdkr1"
type: dpdkr
Port "br0"
Interface "br0"
type: internal
Traffic is from dpdkr2 to dpdkr1.
I have two questions.
1. I observed one interesting behavior.
After running them for a while, sometimes, dpdkr1 got out-of-order packets.
Is it a possible behavior even though I use two dpdkr in a same machine?
2. There are some hardcoded values for ring size and max & min num of
packets for mempool in netdev-dpdk.c.
enum { DPDK_RING_SIZE = 256 };
#define MAX_NB_MBUF (4096 * 64)
#define MIN_NB_MBUF (4096 * 4)
What are the intuition of these values?
Thanks,
