- Use the following command to find the logical name(s) of the Ethernet interfaces on the target Intel® FPGA PAC N3000-N/2:
ls -la /sys/class/net
In the following example, if you want to change settings on the Intel® FPGA PAC N3000-N/2 with PCIe b:d.f 8a:00.0, then ensure that the PCIe device ID for enp136s0f0, enp136s0f1, enp139s0f0 and enp139sof1 is in the range of 88-8b.
