Hello,
For X410 the network adapter which works under DPDK driver control can't
be used to control the device (it can't carry RPC calls to MPM daemon
working on the device). You need a separate Ethernet connection for
mgmt_addr. You can use 1Gbit Ethernet link for that.
Best Regards,
Piotr Krysik

Hi all,
I am trying to enable DPDK with X410 and found an issue when using
“use_dpdk=1”. I am on Ubuntu 22.04, the latest UHD 4.4.0 (commit:
4a77791cf5f7cedc842762be8b2b6775073d8c95) and DPDK 21.11.4.
When the X410 is connect to the interface without DPDK, I can find it
via uhd_usrp_probe and run benchmark_rate without issue. After binding
the NIC to DPDK, the X410 can no longer be found when using DPDK.
Anyone know why it’s disappearing?
Output of find devices before DPDK is enabled:
