[PATCH AUTOSEL 5.1 64/70] net: phy: dp83867: Set up RGMII TX delay

From: Sasha Levin
Date: Sat Jun 08 2019 - 07:46:35 EST


From: Max Uvarov <muvarov@xxxxxxxxx>

[ Upstream commit 2b892649254fec01678c64f16427622b41fa27f4 ]

PHY_INTERFACE_MODE_RGMII_RXID is less then TXID
so code to set tx delay is never called.
