Author: slavash Date: Wed Dec 5 13:27:17 2018 New Revision: 341538 URL: https://svnweb.freebsd.org/changeset/base/341538 Log: ipoib: Notify on modify QP failure only when relevant Modify QP can fail and it can be acceptable, like when moving from RST to ERR state, all the rest are not acceptable and a message to the log should be printed. The current code prints on all failures and many messages like: "Failed to modify QP to ERROR state" appear, even when supported by the state machine of the QP object.
