UHD4.2 & DPDK

[Dobler, Anton]

Dear community,

I try to use DPDK together with UHD4.2 but I get the following error:

./benchmark_rate --args "mgmt_addr=169.254.2.13,addr=1.0.1.2, second_addr=1.0.2.2,use_dpdk=1" --rx_rate=125e6

I use the uhd.conf as follows:

[use_dpdk=1]

dpdk-mtu=9000

dpdk-driver=/usr/lib/x86_64-linux-gnu/dpdk/pmds-20.0/dpdk/

dpdk-corelist=0,9,10

dpdk-num-mbufs=4096

dpdk-mbufs-cache-size=315

;ens2f0

[dpdk-mac=90:e2:ba:f1:38:1c]

dpdk-lcore = 9

dpdk-ipv4 = 1.0.2.1/24

;ens2f1

[dpdk-mac=90:e2:ba:f1:38:1d]

dpdk-lcore = 10

dpdk-ipv4 = 1.0.1.1/24​

Any help would be highly appreciated!

Best regards,
