dpdk 抓包

dump DOC

需要修改源代码

• The dpdk-pdump tool can only be used in conjunction with a primary application which has the packet capture framework initialized already. In dpdk, only the testpmd is modified to initialize packet capture framework, other applications remain untouched. So, if the dpdk-pdump tool has to be used with any application other than the testpmd, user needs to explicitly modify that application to call packet capture framework initialization code. Refer app/test-pmd/testpmd.c code to see how this is done.
• The dpdk-pdump tool depends on DPDK pcap PMD, so the system should have libpcap development files installed and the pcap PMD not disabled in the build.
• The dpdk-pdump tool runs as a DPDK secondary process. It exits when the primary application exits.
• 代码： test-pmd/testpmd.c
