I don't know what exactly 'FX2' device is, but I was referring to
'1d6c:1022' device id.
Following is the device table from latest code [1], is '1d6c:1022'
supported?
static const struct rte_pci_id pci_id_ark_map[] = {
{RTE_PCI_DEVICE(AR_VENDOR_ID, 0x100d)},
{RTE_PCI_DEVICE(AR_VENDOR_ID, 0x100e)},
{RTE_PCI_DEVICE(AR_VENDOR_ID, 0x100f)},
{RTE_PCI_DEVICE(AR_VENDOR_ID, 0x1010)},
{RTE_PCI_DEVICE(AR_VENDOR_ID, 0x1017)},
{RTE_PCI_DEVICE(AR_VENDOR_ID, 0x1018)},
{RTE_PCI_DEVICE(AR_VENDOR_ID, 0x1019)},
{RTE_PCI_DEVICE(AR_VENDOR_ID, 0x101a)},
{RTE_PCI_DEVICE(AR_VENDOR_ID, 0x101b)},
{RTE_PCI_DEVICE(AR_VENDOR_ID, 0x101c)},
{RTE_PCI_DEVICE(AR_VENDOR_ID, 0x101e)},
{RTE_PCI_DEVICE(AR_VENDOR_ID, 0x101f)},
{.vendor_id = 0, /* sentinel */ },
};
