framework initialization code. Refer ``app/test-pmd/testpmd.c``
code to see how this is done.
- * The ``dpdk-pdump`` tool depends on libpcap based PMD which is disabled
- by default in the build configuration files,
- owing to an external dependency on the libpcap development files
- which must be installed on the board.
- Once the libpcap development files are installed, the libpcap based PMD
- can be enabled by setting CONFIG_RTE_LIBRTE_PMD_PCAP=y and recompiling the DPDK.
+ * 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.
