Subject: [v2 net PATCH 4/5] octeontx2-pf: Send UP messages to VF only when VF is up.
Date: Mon, 18 Mar 2024 14:59:57 +0530 [thread overview]
Message-ID: <1710754198-18632-5-git-send-email-sbhatta@marvell.com> (raw)
In-Reply-To: <1710754198-18632-1-git-send-email-sbhatta@marvell.com>
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.
Fixes: ad513ed938c9 ("octeontx2-vf: Link event notification support")
