Subject: [PATCH] ethernet:ti:cpsw: fix phy identification with multiple slaves on fixed-phy
Date: Fri, 04 Dec 2015 16:55:17 +0100	[thread overview]
Message-ID: <5661B765.3050504@iktek.de> (raw)

When using more than one slave with ti cpsw and fixed phy the pd->phy_id 
will be always zero, but slave_data->phy_id must be unique.
pd->phy_id means a "phy hardware id" whereas slave_data->phy_id means an 
"unique id", so we should use pd->addr which has the same unique meaning.
