+Subject: [PATCH] net: phy: broadcom: support new device flag for setting
+ master mode
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Some of Broadcom's PHYs run by default in slave mode with Automatic
+Slave/Master configuration disabled. It stops them from working properly
+with some devices.
+
+So far it has been verified for BCM54210E and BCM50212E which don't
+work well with Intel's I217-LM and I218-LM:
+http://ark.intel.com/products/60019/Intel-Ethernet-Connection-I217-LM
+http://ark.intel.com/products/71307/Intel-Ethernet-Connection-I218-LM
+I was told there is massive ping loss.
+
+This commit adds support for a new flag which can be set by an ethernet
+driver to fixup PHY setup.
