XAUI allows XGMII to reach an extended distance by using a XGXS layer at each end of the MAC to PHY link, operating over four Serdes lanes. 10GBASE-KR is a single lane Serdes backplane ethernet connection method with autonegotiation on the link. Some PHYs use this to connect to the ethernet interface at 10G speeds, switching to other connection types when utilising slower speeds. 10GBASE-KR is also used for XFI and SFI to connect to XFP and SFP fiber modules.

2017-05-28net: phy: Relax error checking on sysfs_create_link()Florian Fainelli1-0/+2
Some Ethernet drivers will attach/connect to a PHY device before calling register_netdevice() which is responsible for calling netdev_register_kobject() which would do the network device's kobject initialization. In such a case, sysfs_create_link() would return -ENOENT because the network device's kobject is not ready yet, and we would fail to connect to the PHY device. In order to keep things simple and symetrical, we just take the success path as indicative of the ability to access the network device's kobject, and create the second link if that's the case.

2017-04-26net: phy: fix auto-negotiation stall due to unavailable interruptAlexander Kochetkov1-0/+1
The Ethernet link on an interrupt driven PHY was not coming up if the Ethernet cable was plugged before the Ethernet interface was brought up. The patch trigger PHY state machine to update link state if PHY was requested to do auto-negotiation and auto-negotiation complete flag already set. During power-up cycle the PHY do auto-negotiation, generate interrupt and set auto-negotiation complete flag. Interrupt is handled by PHY state machine but doesn't update link state because PHY is in PHY_READY state. After some time MAC bring up, start and request PHY to do auto-negotiation. If there are no new settings to advertise genphy_config_aneg() doesn't start PHY auto-negotiation. PHY continue to stay in auto-negotiation complete state and doesn't fire interrupt. At the same time PHY state machine expect that PHY started auto-negotiation and is waiting for interrupt from PHY and it won't get it.

2017-04-24mdio_bus: Issue GPIO RESET to PHYs.Roger Quadros1-0/+7
Some boards [1] leave the PHYs at an invalid state during system power-up or reset thus causing unreliability issues with the PHY which manifests as PHY not being detected or link not functional. To fix this, these PHYs need to be RESET via a GPIO connected to the PHY's RESET pin. Some boards have a single GPIO controlling the PHY RESET pin of all PHYs on the bus whereas some others have separate GPIOs controlling individual PHY RESETs. In both cases, the RESET de-assertion cannot be done in the PHY driver as the PHY will not probe till its reset is de-asserted. So do the RESET de-assertion in the MDIO bus driver.

2017-03-24net: phy: Allow splitting MDIO bus/device support from PHYsFlorian Fainelli1-2/+19
Introduce a new configuration symbol: MDIO_DEVICE which allows building the MDIO devices and bus code, without pulling in the entire Ethernet PHY library and devices code. PHYLIB nows select MDIO_DEVICE and the relevant Makefile files are updated to reflect that. When MDIO_DEVICE (MDIO bus/device only) is selected, but not PHYLIB, we have mdio-bus.ko as a loadable module, and it does not have a module_exit() function because the safety of removing a bus class is unclear. When both MDIO_DEVICE and PHYLIB are enabled, we need to assemble everything into a common loadable module: libphy.ko because of nasty circular dependencies between phy.c, phy_device.c and mdio_bus.c which are really tough to untangle.

The Generic PHY driver is a catch-all PHY driver and it should preserve whatever prior initialization has been done by boot loader or firmware agents. For specific PHY device configuration it is expected that a specialized PHY driver would take over that role.
