Dear all,

I came across an issue with the ip link command that in the end boiled
down to an incomplete manpage entry:

---
ip link set { DEVICE | group GROUP }
---

This is missing one option (the "dev" part) compared to the help page (ip
link help):

---
ip link set { DEVICE | dev DEVICE | group DEVGROUP }
---

I surely lost a few hairs the other day because my vpn features a tap
interface named "dev" (for the "development" network), and to my surprise
"ip link set dev up" complained about device "up" not being found as the
"dev" part got eaten away by the parser due to the extra syntax I didn't
know about. ;)
It would be great if this could be fixed in the manpage to avoid confusion.
