The page http://dpdk.org/doc/nics says that 8254x should be supported. But looking in details: % grep 'RTE_PCI_DEV_ID_DECL.*8254' lib/librte_eal/common/include/rte_pci_dev_ids.h RTE_PCI_DEV_ID_DECL_EM(PCI_VENDOR_ID_INTEL, E1000_DEV_ID_82540EM) RTE_PCI_DEV_ID_DECL_EM(PCI_VENDOR_ID_INTEL, E1000_DEV_ID_82545EM_COPPER) RTE_PCI_DEV_ID_DECL_EM(PCI_VENDOR_ID_INTEL, E1000_DEV_ID_82545EM_FIBER) It means that only 82540 and 82545 are supported. I don't know if there is a big difference with 82546 controller and I'm not aware of any plan to support it. So feel free to try and patch it. -- Thomas
