Subject: [PATCH net] openvswitch: warn about missing first netlink attribute
Date: Thu,  8 Jun 2017 10:37:45 +0200	[thread overview]
Message-ID: <1496911065-6912-1-git-send-email-nicolas.dichtel@6wind.com> (raw)

The first netlink attribute (value 0) must always be defined
as none/unspec.

Because we cannot change an existing UAPI, I add a comment to point the
mistake and avoid to propagate it in a new ovs API in the future.
