Subject: [PATCH v1 net] lan743x: Expand phy search for LAN7431
Date: Mon, 17 Dec 2018 16:44:50 -0500	[thread overview]
Message-ID: <1545083090-31529-1-git-send-email-Bryan.Whitehead@microchip.com> (raw)

The LAN7431 uses an external phy, and it can be found anywhere in
the phy address space. This patch uses phy address 1 for LAN7430
only. And searches all addresses otherwise.
