net: phy: broadcom: support new device flag for setting master mode
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. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: David S. Miller <davem@davemloft.net>
