Re: [dpdk-dev] How to run intel dpdk apps on '82574L Gigabit Network Connection' NIC cards

Hi Ayon

Good to see that!
DPDK just has only one driver of igb_uio to bind NICs. VFIO is another story. You don’t have choices.

Please read the online documents for more details and steps of using DPDK!

hi,
its OK, which driver i need to bind to this NIC??
./lib/librte_pmd_e1000/e1000/e1000_hw.h:95:
#define E1000_DEV_ID_82574L 0x10D3
Regards.

Hi Ayon

1521 is the device ID of my NIC, yours is 10d3. So you need to check if 10d3 is listed in that file or not, but not checking 1521.

hi,

lspci -nn | grep Eth
02:00.0 Ethernet controller [0200]: Intel Corporation 82574L Gigabit Network Connection [8086:10d3]
03:00.0 Ethernet controller [0200]: Intel Corporation 82574L Gigabit Network Connection [8086:10d3]
04:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 06)
and in ./x86_64-default-linuxapp-gcc/include/rte_pci_dev_ids.h

#define E1000_DEV_ID_I350_COPPER                0x1521
is present.

Check the device ID can know if your NIC is supported by dpdk or not.

"Lspci -nn | grep Eth" will show like below, 1521 is the device ID.
04:00.0 Ethernet controller [0200]: Intel Corporation I350 Gigabit Network Connection [8086:1521]
Then check rte_pci_dev_ids.h to see if that device ID is listed in that file or not, then you know if your NIC is supported or not.
