Hi, we now installed DPDK 17.11 but I still have exactly the same problem.
I have a feeling the problem is that I am not addressing the device correctly. Here is what I did:
The USRP is connected to ethernet interfaces "p1p2" (mac_addr 64:9d:99:b1:1e:8d) and "p1p4" (mac_addr 64:9d:99:b1:1e:8f) which are originally configured with IP addresses 192.168.10.1 and inet_addr 192.168.20.1. This configuration works fine without dpdk.
Then I deactivate these two interfaces using "ifconfig p1p2 down" "ifconfig p1p4 down"and do "dpdk-devbind --bind=vfio-pci 01:00.1" and "dpdk-devbind --bind=vfio-pci 01:00.3". The status of "dpdk-devbind -s" is below.
In the file /etc/uhd/uhd.conf I specify [dpdk_mac=64:9d:99:b1:1e:8d] dpdk_io_cpu = 1 dpdk_ipv4 = 192.168.10.1/24 [dpdk_mac=64:9d:99:b1:1e:8f] dpdk_io_cpu = 2 dpdk_ipv4 = 192.168.20.1/24Is this the correct way of specifying it? What surprises me is that DPDK requires to address the device by its PCI address while UHD still requires to set the IP addresses.

Hello all,Is this problem fixed? If yes, could you please tell how? We have a similar error, so it would be helpful.Thanks and regards, Akın3 Oca 2020 Cum 23:22 tarihinde Sam Reiter via USRP-users <usrp-users@lists.ettus.com <mailto:usrp-users@lists.ettus.com>> şunu yazdı:Florian, DPDK 18.11 is not supported on UHD 3.x.
