Thank you for your review and comment. My takeaway here is that the test works because the IP addresses are set on the $devdummy by the previous ip(8) command, and ifconfig seems a bit redundant. Also, considering we are testing netlink, I was baffled to see ifconfig there that, if I'm not mistaken, uses ioctl(); but I might be missing something obvious here, considering I'm looking at these tests for the first time, so bear with me :) If it's better to skip the test altogether when ifconfig is missing, I'll submit another patch to do so. Thank you Best regards, Alessandro
