Hi,
We have noticed that i40e if we do PCI-pass through of whole NIC to VM on
ESXi 6.0, the DPDK exits abruptly in rte_eal_init()?
We are passing following parameters:
char *eal_argv[] = {"fakeelf",
"-c2",
"-n4",
"--proc-type=primary",};
int ret = rte_eal_init(4, eal_argv);
The code works with Intel '82599ES 10-Gigabit SFI/SFP+ ' adapter in
PCI-passthrough or SR-IOV mode however i40e it does not work.

1500 Intel Corporation Ethernet Controller X710 for 10GbE SFP+
We have turned on following config in DPDK:
CONFIG_RTE_PCI_CONFIG=y
CONFIG_RTE_PCI_EXTENDED_TAG="on"
CONFIG_RTE_LIBRTE_I40E_16BYTE_RX_DESC=y
Is there any special handling in DPDK for i40e adapter in terms of config?
Thanks,
