RARE user and assistance email list

No improvement, the interface is still down.

I decided to change the user from freerouter to root in the systemd file /usr/lib/systemd/system/freerouter.service, now I get the following error:

So I decided to run  /bin/p4dpdk.bin --vdev=net_af_packet1,iface=veth0b -- 127.0.0.1 9080 2 manually and I got the promiscuous error:

[root@ip-172-31-38-199 log]# /bin/p4dpdk.bin --vdev=net_af_packet1,iface=veth0b -- 127.0.0.1 9080 2 EAL: Detected CPU lcores: 8 EAL: Detected NUMA nodes: 1 EAL: Detected shared linkage of DPDK EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'PA' EAL: No available 1048576 kB hugepages reported EAL: VFIO support initialized EAL: Using IOMMU type 8 (No-IOMMU) EAL: Probe PCI driver: net_ena (1d0f:ec20) device: 0000:00:06.0 (socket 0) EAL: Probe PCI driver: net_ena (1d0f:ec20) device: 0000:00:07.0 (socket 0) TELEMETRY: No legacy callbacks, legacy socket not created 8 cores and 3 ports detected... dpdk version: DPDK 21.11.2 openssl version: OpenSSL 1.1.1g FIPS 21 Apr 2020 connecting 127.0.0.1 9080. cpu port is #2 of 3... there will be 0 forwarding only cores... there will be 8191 mbufs, each 2048 bytes, 250 cached... there will be 1024 rx and 1024 tx descriptors, 512 tx and 512 fwd mbufs... there will be 32 bursts and maybe 100 sleeps... opening mempool on socket 0... opening port 0 named 0000:00:06.0 on socket 0 on lcore 0 for rx and 0 for tx... devinfo: pmd=net_ena, mtu=128..9216, bufs=64, pktl=9234, rxque=10, txque=8, rxcapa=0000200e, txcapa=0000800e... configuring port: offloads rx=00002000, tx=00008000, pktlen=2048 EAL: Error - exiting with code: 1 Cause: error setting promiscuous mode

N.B - I have tested the dpdk interfaces in VPP and it works.
