Subject: [PATCH] net: phy: dp83867: Explicitly check against sgmii
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

dp83867 driver only supports sgmii and not all the newer protocols.
Drop the usage of the generic phy_interface_is_sgmii function and just
matchup to the specific mode supported.
