| 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. | ||
