This is especially true with serdes links, +where the part of the PHY is effectively integrated into the MAC. + +Serdes links can be connected to a variety of devices, including SFF +modules soldered down onto the board with the MAC, a SFP cage with +a hotpluggable SFP module which may contain a PHY or directly modulate +the serdes signals onto optical media with or without a PHY, or even +a classical PHY connection. + +Moreover, the negotiation information on serdes links comes in two +varieties - SGMII mode, where the PHY provides its speed/duplex/flow +control information to the MAC, and 1000base-X mode where both ends +exchange their abilities and each resolve the link capabilities. + +This means we need a more flexible means to support these arrangements, +particularly with the hotpluggable nature of SFP, where the PHY can +be attached or detached after the network device has been brought up. + +Ethtool information can come from multiple sources: +- we may have a PHY operating in either SGMII or 1000base-X mode, in + which case we take ethtool/mii data directly from the PHY. +- we may have a optical SFP module without a PHY, with the MAC + operating in 1000base-X mode - the ethtool/mii data needs to come + from the MAC. +- we may have a copper SFP module with a PHY whic can't be accessed, + which means we need to take ethtool/mii data from the MAC. + +Phylink aims to solve this by providing an intermediary between the +MAC and PHY, providing a safe way for PHYs to be hotplugged, and +allowing a SFP driver to reconfigure the serdes connection. + +Phylink also takes over support of fixed link connections, where the +speed/duplex/flow control are fixed, but link status may be controlled +by a GPIO signal. By avoiding the fixed-phy implementation, phylink +can provide a faster response to link events: fixed-phy has to wait for +phylib to operate its state machine, which can take several seconds. +In comparison, phylink takes milliseconds. + +Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> + +- remove sync status +- rework supported and advertisment handling +- add 1000base-x speed for fixed links +- use functionality exported from phy-core, reworking + __phylink_ethtool_ksettings_set for it +--- + create mode 100644 drivers/net/phy/phylink.c + create mode 100644 include/linux/phylink.h + +--- a/drivers/net/phy/Kconfig ++++ b/drivers/net/phy/Kconfig +@@ -10,6 +10,16 @@ menuconfig PHYLIB + devices.
