Subject: [PATCH v3 13/25] net/axgbe: fix the false linkup in axgbe PHY status
Date: Tue, 4 Jun 2024 17:41:45 +0530	[thread overview]
Message-ID: <20240604121157.3052-13-venkatkumar.ande@amd.com> (raw)
In-Reply-To: <20240604121157.3052-1-venkatkumar.ande@amd.com>

From: Venkat Kumar Ande <VenkatKumar.Ande@amd.com>

In the event of a change in AXGBE mode, the current auto-negotiation
needs to be reset and the AN cycle needs to be re-triggered. However,
the current code ignores the return value of axgbe_set_mode(), leading to
false information as the link is declared without checking the status
register.

Fix this by propagating the mode switch status information to
axgbe_phy_status().

Fixes: 102b6ec3d5c3 ("net/axgbe: support auto-negotiation for 1Gbps")
