The patch is well defined but it doesn't provide user with the answer to the question "why is the SFP still up if I asked it to be down?"
Can the user even see that the SFP is still up? Does ip link show
give:
3: eth42: <BROADCAST,MULTICAST,LOWER_UP> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
i.e. LOWER_UP despite DOWN?
Roopa added:
rtnetlink: add support for protodown reason
Maybe we need the opposite as well?
