- Subject: [PATCH] net: dsa: populate supported_interfaces member
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- Add a new DSA switch operation, phylink_get_interfaces, which should
- fill in which PHY_INTERFACE_MODE_* are supported by given port.
- Use this before phylink_create() to fill phylinks supported_interfaces
- member, allowing phylink to determine which PHY_INTERFACE_MODEs are
- supported.
