Re: [vpp-dev] #vpp How does VPP link DPDK lib？
Hi Wei, DPDK links(static) as part of the dpdk plugin in VPP. You can do readelf on dpdk_plugin.so Thanks Shiva On Fri, Nov 29, 2019 at 11:20 AM wrote: > We think VPP uses DPDK for data receive from nic, but it seems no dpdk lib > exist in vpp project. > we also try to use readelf to check the libs used by vpp, or use strings > check the functions in each lib.

[vpp-dev] #vpp How does VPP link DPDK lib？
We think VPP uses DPDK for data receive from nic, but it seems no dpdk lib exist in vpp project. we also try to use readelf to check the libs used by vpp, or use strings check the functions in each lib. We did not find how dpdk is used. So can you please give some guide, how does vpp link dpdk lib?
