Hi,
I’m trying to conduct the UHD benchmark test using DPDK on X410 radio. I’m
using the NI Dual 100 Gigabit Ethernet PCIe NIC card, using the Mellanox
drivers, and have the UC_200 fpga image loaded on the radio. However, I keep
experiencing packet drops and sequence errors when I do that. Any idea why
that’s happening?
/usr/local/lib/uhd/examples$ sudo ./benchmark_rate --args
"type=x4xx,product=x410,addr=192.168.20.3,mgmt_addr=192.168.1.3,use_dpdk=1"
--priority "high" --multi_streamer --rx_rate 245.76e6 --rx_subdev "B:1"
--tx_rate 245.76e6 --tx_subdev "B:0"
