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
