[dpdk-users] pdump process failed in bnx2x_common_dev_init.

Hi,
I'm trying to use dpdk-pdump with dpdk-stable-18.02.1.

my configurations:

CONFIG_RTE_LIBRTE_BNX2X_PMD=y
CONFIG_RTE_LIBRTE_BNX2X_DEBUG_RX=y
CONFIG_RTE_LIBRTE_BNX2X_DEBUG_TX=y
CONFIG_RTE_LIBRTE_BNX2X_MF_SUPPORT=y
CONFIG_RTE_LIBRTE_BNX2X_DEBUG_PERIODIC=y
CONFIG_RTE_LIBRTE_PMD_PCAP=y
CONFIG_RTE_LIBRTE_PDUMP=y


I bind the device to DPDK:

 Network devices using DPDK-compatible driver
============================================
0000:03:00.1 'NetXtreme II BCM57810 10 Gigabit Ethernet 168e' drv=igb_uio
unused=vfio-pci



And I start the primary process first:

However, the secondary process failed.

Have I missed something? Please give me some information to understand this
issue.
