Subject: [PATCH 001/145] net: socionext: Reset tx queue in ndo_stop |
| 5 |
|
|
|
| 6 |
|
|
[ Upstream commit 8d5b0bf611ec5b7618d5b772dddc93b8afa78cb8 ] |
| 7 |
|
|
|
| 8 |
|
|
We observed that packets and bytes count are not reset |
| 9 |
|
|
when user performs interface down. Eventually, tx queue is |
| 10 |
|
|
exhausted and packets will not be sent out. |
| 11 |
|
|
To avoid this problem, resets tx queue in ndo_stop. |
