wishbone-tool throws a socket error and cannot connect

[lindemer]

I have LiteX running on an Arty board, which was flashed using the following command: /arty.py --cpu-type=vexriscv --cpu-variant=full+debug --with-etherbone --build --load. It's connected via an Ethernet-USB adapter, which I've configured using the following:

sudo ip link set dev enx9cebe8612341 down
sudo ip addr add 192.168.1.100/24 dev enx00249b284adc
sudo ip link set dev enx9cebe8612341 up

This gives me the following:

$ ip route
default via 10.0.2.2 dev enp0s3 proto dhcp metric 100
10.0.2.0/24 dev enp0s3 proto kernel scope link src 10.0.2.15 metric 100
169.254.0.0/16 dev enp0s3 scope link metric 1000
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 linkdown
192.168.1.0/24 dev enx00249b284adc proto kernel scope link src 192.168.1.100

I can now ping the board at 192.168.1.50, but I can't reach it with wishbone-tool --ethernet-host 192.168.1.50 -s gdb. I get the following error every time: Error: "invalid configuration: invalid ethernet address: io error invalid socket address". I've been stuck on this for a while (see enjoy-digital/litex#676) and am now quite confident it's an issue with wishbone-tool and not LiteX.

Edit I've built everything from the latest source as of today (LiteX and wishbone-utils).
