| 8 | [ Upstream commit e15aa3b2b1388c399c1a2ce08550d2cc4f7e3e14 ] | |
| 9 | ||
| 10 | After a timeout event caused by for example a broadcast storm, when | |
| 11 | the MAC and PHY are reset, the BQL TX queue needs to be reset as | |
| 12 | well. Otherwise, the device will exhibit severe performance issues | |
| 13 | even after the storm has ended. | |
