| Subject: octeontx2-pf: Send UP messages to VF only when VF is up. |
| |
| From: Subbaraya Sundeep <sbhatta@marvell.com> |
| |
| [ Upstream commit dfcf6355f53b1796cf7fd50a4f27b18ee6a3497a ] |
| |
| When PF sending link status messages to VF, it is possible |
| that by the time link_event_task work function is executed |
| VF might have brought down. Hence before sending VF link |
| status message check whether VF is up to receive it. |
