[dpdk-users] Failed to initialize one specific port of X710-DA4 in i40e pmd

[Hitoshi Masutani]

I am facing a failure of dpdk(16.11.3) initialization with testpmd
using i40e pmd on a specific physical port of X710-DA4.

Without such specific port, testpmd can run successfully.

My server box has two X710-DA4 cards and
these two cards have the same failure.

To clarify whether it is caused by hardware failure or
by the lack of appropriate nic configuration,
the following build options of dpdk are enabled.

--------------
CONFIG_RTE_LIBRTE_ETHDEV_DEBUG=y
CONFIG_RTE_LIBRTE_I40E_DEBUG_INIT=y
CONFIG_RTE_LIBRTE_I40E_DEBUG_DRIVER=y
--------------

My server box spec. is as follows :

CPU        : Intel(R) Xeon(R) Gold 6136
MEMORY     : 128GB (16G x 8)
Motherboard: SYS-1029U-TR4
NIC1       : I350 x 4 (onboard nic)
NIC2       : XL710 dual
NIC3       : X710-DA4
NIC4       : X710-DA4
------------------------------------------------------------
OS         : ubnutu 16.04.3 LTS(linux-image-4.4.0-87-generic)
DPDK       : 16.11.3

testpmd's boot message is as follows :
