- 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.
