From dfcf6355f53b1796cf7fd50a4f27b18ee6a3497a Mon Sep 17 00:00:00 2001 From: Subbaraya Sundeep Date: Mon, 18 Mar 2024 14:59:57 +0530 Subject: octeontx2-pf: Send UP messages to VF only when VF is up. 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.
