Hi, VPP doesn't see mellanox 40G card. I've try to compile based on summary instruction https://lists.fd.io/g/vpp-dev/message/16211 But after recompilation it doesn't see NIC in show interface
The main problem that there is no message in log like for intel card /usr/bin/vpp[394111]: pci: Skipping PCI device 0000:02:00.0 as host interface eno1 is up $ cat /etc/os-release NAME="Ubuntu" VERSION="20.04.2 LTS (Focal Fossa) # lshw -c network -businfo Bus info Device Class Description ======================================================= pci@0000:01:00.0 enp1s0f0 network MT27700 Family [ConnectX-4] pci@0000:01:00.1 enp1s0f1 network MT27700 Family [ConnectX-4] # lsmod | grep mlx mlx5_ib 331776 0 ib_uverbs 147456 1 mlx5_ib ib_core 352256 2 ib_uverbs,mlx5_ib mlx5_core 1105920 1 mlx5_ib pci_hyperv_intf 16384 1 mlx5_core mlxfw 32768 1 mlx5_core tls 90112 1 mlx5_core Building: # git clone https://gerrit.fd.io/r/vpp # make install-dep After building vpp, I try to run $ sudo ifconfig enp1s0f1 down $ sudo LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/login/origin/build-root/install-vpp_debug-native/external/lib/ ./build-root/build-vpp_debug-native/vpp/bin/vpp -c ./build-root/install-vpp_debug-native/vpp/etc/vpp/startup.conf Then go to console $ sudo LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/login/origin/build-root/install-vpp_debug-native/external/lib/ ./build-root/build-vpp_debug-native/vpp/bin/vppctl DBGvpp# show interface Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count local0 0 down 0/0/0/0 DBGvpp# show pci Address Sock VID:PID Link Speed Driver Product Name Vital Product Data 0000:01:00.0 0 15b3:1013 8.0 GT/s x8 mlx5_core CX414A - ConnectX-4 QSFP28 PN: MCX414A-GCAT EC: AG SN: MT2002X14876 V0: 0x 50 43 49 65 47 65 6e 33 ...

RV: 0x 28 00 00 As you can see there is no 40G interface in VPP. Maybe be there is some specific prerequisites, OS or driver version?
