Subject: [PATCH net v2 3/3] ibmvnic: skip tx timeout reset while in resetting
Date: Fri, 20 Nov 2020 16:40:13 -0600 [thread overview]
Message-ID: <20201120224013.46891-4-ljp@linux.ibm.com> (raw)
In-Reply-To: <20201120224013.46891-1-ljp@linux.ibm.com>
Sometimes it takes longer than 5 seconds (watchdog timeout) to complete
failover, migration, and other resets. In stead of scheduling another
timeout reset, we wait for the current one to complete.
