+Subject: [PATCH 3/4] tg3: APE heartbeat changes
+
+In ungraceful host shutdown or driver crash case BMC connectivity is
+lost. APE firmware is missing the driver state in this
+case to keep the BMC connectivity alive.
+This patch has below change to address this issue.
+
+Heartbeat mechanism with APE firmware. This heartbeat mechanism
+is needed to notify the APE firmware about driver state.
+
+This patch also has the change in wait time for APE event from
+1ms to 20ms as there can be some delay in getting response.
+
+v2: Drop inline keyword as per David suggestion.
