[v2 net PATCH 4/5] octeontx2-pf: Send UP messages to VF only when VF is up.

From: Subbaraya Sundeep
Date: Mon Mar 18 2024 - 05:32:00 EST


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.
