ip addr add command generates error

ip addr add command generates error

[Rose, Gregory V]

The 'ip addr add' command used to use the following syntax:

# ip addr add 10.0.0.2/24 brd 10.0.0.255 dev <eth>

However, attempts to use that same command syntax with the current iproute2 tip gives the following error:

Error: an inet prefix is expected rather than "20.0.0.2/24"

This seems like a bug.  The commit that introduces the issue is f3a2ddc124e09d3990b836e322ed39c76c35546e by Vadim Kochan.  Reverting this commit fixes the problem.

Is this change deliberate?  It would break a lot of scripts if so.

Thanks,

- Greg

looked like an unintended change. This was reported a few days back and 
I hit this too in another context and a patch 
https://patchwork.ozlabs.org/patch/451210/ is in the queue.

I apologize for this stupid mistake!
