Re: [dpdk-users] DPDK Pdump support for the external buffers - 20_11 version

[Navin Srinivas <g.navinsrinivas@gmail.com>]

Hi,

I managed to debug further and noticed that *pmd_pcap_drv* is not loaded on
our application, which is available in test-pmd when the attach is called
from secondary application dpdk-pdump

How do I enable the pmd_pcap_drv in vdev ? We have done rte_pdump_init as
suggested by the DPDK documentation.

Am I missing some init ?

Thanks & Regards,
Navin Srinivas
