[ovs-discuss] Which function/struct can I use to parse the Src/Dst IP in OVS source code while using DPDK?

2017-11-08 Thread 施谷燁 
Hi,

I'm trying to add a sketch in OVS to get statistics for source and
destination IP address while using DPDK.

As I know the packet will first arrive Network Interface Card(NIC) then use
Poll Mode Drive(PMD)(library in *netdev-dpdk.c*) to pass the packet to
*dpif-netdev.c* then go through match process like *emc_processing(),
fast_path_processing() and packet_batch_per_flow_excute()*.

I want to get the Src/Dst IP information ASAP after DPDK pass the packet
into user space. What I guess is the function or struct to parse the
Src/Dst IP is in *dpif-netdev.c*.
Is anyone know which exact function/struct can I use to get the IP
information here?

Thanks
Glenn

Re: [ovs-discuss] OVN patch port for localnet can't be created

2017-11-08 Thread Numan Siddique 
Is this openstack setup with networking-ovn ?

Can you run "ovn-nbctl list logical_router_port | grep redirect-chassis"
and make sure that networking-ovn has scheduled the gateway router port to
the desired chassis ?

May be the gateway router port is scheduled to some other chassis.

You can can run "ovn-nbctl set logical_router_port
options:redirect-chassis="CHASSIS_UUID_WHERE_YOU_WANT_TO_SCHEDULE" to
schedule it to your desired chassis.

Thanks
Numan

http://openvswitch.org/support/dist-docs/ovs-ofctl.8.txt
and look for the Flow Syntax section.

Also:
