Subject: [PATCH] net/cnxk: toggle link status for representors
Date: Thu, 14 Nov 2024 15:09:15 +0530	[thread overview]
Message-ID: <20241114093915.180971-1-hkalra@marvell.com> (raw)

Representor port link status should be toggled based on representee
state i.e. if representee comes up representor link status should be
up while when representee goes down representor port should indicate
the same.
