Johannes Berg ba0dc5f6e0 netlink: allow sending extended ACK with cookie on success ... Now that we have extended error reporting and a new message format for netlink ACK messages, also extend this to be able to return arbitrary cookie data on success. This will allow, for example, nl80211 to not send an extra message for cookies identifying newly created objects, but return those directly in the ACK message. The cookie data size is currently limited to 20 bytes (since Jamal talked about using SHA1 for identifiers.) Thanks to Jamal Hadi Salim for bringing up this idea during the discussions.
