From ebc9ca43e1d52a85c72fc2d343f353386ed6c188 Mon Sep 17 00:00:00 2001 From: Tadeusz Struk Date: Mon, 29 May 2017 17:20:53 -0700 Subject: [PATCH] IB/core: Allow QP state transition from reset to error Playing with IP-O-IB interface can trigger a warning message: "ib0: Failed to modify QP to ERROR state" to be logged. This happens when the QP is in IB_QPS_RESET state and the stack is trying to transition it to IB_QPS_ERR state in ipoib_ib_dev_stop(). According to the IB spec, Table 91 - "QP State Transition Properties" it looks like the transition from reset to error is valid: Transition: Any State to Error Required Attributes: None Optional Attributes: None allowed Actions: Queue processing is stopped. Work Requests pending or in process are completed in error, when possible. This patch allows the transition and quiets the message.
