Hi, We have a NetXtreme BCM5719 NIC (pci address:0000:02:00.1) on our machine. When we execute "python /opt/vpp/external/x86_64/share/dpdk/usertools/dpdk-devbind.py --status" the output we get is :- Network devices using kernel driver =================================== *0000:02:00.1* 'NetXtreme BCM5719 Gigabit Ethernet PCIe 1657' if=eno2 drv=tg3 unused=vfio-pci,uio_pci_generic
We white listed this interface in /etc/vpp/startup.conf, brought the interface down and restarted the vpp. But we on executing " vppctl show int ", the interface is not showing in vpp :- *vppctl show int* Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count local0 0 down 0/0/0/0 On investing this, we found a link ( https://lists.fd.io/g/vpp-dev/topic/vpp_does_not_detect_nic/10642649?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,120,10642649 ) stating that on changing the driver to "uio_pci_generic", the interface could be made visible in VPP. So , we executed "python /opt/vpp/external/x86_64/share/dpdk/usertools/dpdk-devbind.py --bind uio_pci_generic 0000:02:00.1" and restarted the VPP. But on executing " vppctl show int ", the interface is again now showing in vpp :- vppctl show int Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count local0 0 down 0/0/0/0 Also, the driver has been changed to " uio_pci_generic " as shown below :- *[root@vpphost2 vpp]# python /opt/vpp/external/x86_64/share/dpdk/usertools/dpdk-devbind.py --status* Network devices using DPDK-compatible driver ============================================ *0000:02:00.1 '* NetXtreme BCM5719 Gigabit Ethernet PCIe 1657' drv=uio_pci_generic unused=tg3,vfio-pci Network devices using kernel driver =================================== On further investing this, we found a few links :- https://lists.fd.io/g/vpp-dev/topic/attaching_broadcom_nic_to/10640426?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,1,60,10640426 https://doc.dpdk.org/guides/nics/bnxt.html that states that NetXtreme BCM5719 NIC is not supported by DPDK. but these are pretty old posts, What is the status now? Does DPDK support NetXtreme BCM5719 NIC? and If yes, what are we doing wrong on the configuration part?
