Hello, Trying to get an Intel adapter to work with VPP and cannot figure out the error. Any help is welcome and appreciated!
Adapter: Intel(R) Ethernet Network Adapter E810-XXVDA2, driver: ice (version: 5.13.0-40-generic) VPP: v22.02 Linux: kernel 5.13.0-40-generic, Ubuntu focal 20.04.3 LTS When I use the adapter outside of VPP, it works just fine. But when interface is specified in /etc/vpp/startup.conf and started with vppctl, I see this in vpp (error on last line): Is the error -1 as in EIO? vpp# show hardware-interfaces TwentyFiveGigabitEthernet37/0/0 Name Idx Link Hardware TwentyFiveGigabitEthernet37/0/0 1 up TwentyFiveGigabitEthernet37/0/0 Link speed: 25 Gbps RX Queues: queue thread mode 0 main (0) polling Ethernet address b4:96:91:a5:d0:0a Intel E810 Family carrier up full duplex max-frame-size 9018 flags: maybe-multiseg tx-offload intel-phdr-cksum rx-ip4-cksum Devargs: rx: queues 1 (max 64), desc 1024 (min 64 max 4096 align 32) tx: queues 1 (max 64), desc 1024 (min 64 max 4096 align 32) pci: device 8086:159b subsystem 8086:0003 address 0000:37:00.00 numa 0 max rx packet len: 9728 promiscuous: unicast off all-multicast off vlan offload: strip off filter off qinq off rx offload avail: vlan-strip ipv4-cksum udp-cksum tcp-cksum qinq-strip outer-ipv4-cksum vlan-filter vlan-extend scatter timestamp keep-crc rss-hash rx offload active: ipv4-cksum scatter tx offload avail: vlan-insert ipv4-cksum udp-cksum tcp-cksum sctp-cksum tcp-tso outer-ipv4-cksum qinq-insert multi-segs mbuf-fast-free outer-udp-cksum tx offload active: ipv4-cksum udp-cksum tcp-cksum multi-segs rss avail: ipv4-frag ipv4-tcp ipv4-udp ipv4-sctp ipv4-other ipv4 ipv6-frag ipv6-tcp ipv6-udp ipv6-sctp ipv6-other ipv6 l2-payload rss active: none tx burst mode: Scalar tx burst function: (not available) rx burst mode: Scalar rx burst function: (not available) rx bytes ok 2613819 rx missed 18468 Errors: rte_eth_dev_start[port:0, errno:-5]: Unknown error -5 rte_eth_dev_start[port:0, errno:-5]: Unknown error -5
