| Subject: ice: ignore dropped packets during init |
| |
| From: Jesse Brandeburg <jesse.brandeburg@intel.com> |
| |
| commit 28dc1b86f8ea9fd6f4c9e0b363db73ecabf84e22 upstream. |
| |
| If the hardware is constantly receiving unicast or broadcast packets |
| during driver load, the device previously counted many GLV_RDPC (VSI |
| dropped packets) events during init. This causes confusing dropped |
| packet statistics during driver load. The dropped packets counter |
| incrementing does stop once the driver finishes loading. |
| |
| Avoid this problem by baselining our statistics at the end of driver |
| open instead of the end of probe. |
| |
