2016-01-28net: phy: introduce a quirk PHY_FLAG_BROKEN_RESETShaohui Xie
Current driver always performs a phy soft reset when connecting the phy device, but soft reset is not always supported by a phy device, so introduce a quirk PHY_FLAG_BROKEN_RESET to let such a phy device to skip soft reset. This commit uses 'flags' of phy device structure to store the quirk. Signed-off-by: Shaohui Xie <Shaohui.Xie@nxp.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
2016-01-28net: phy: micrel: fix divisor value for KSZ9031 phy skewDinh Nguyen
The picoseconds to register value divisor(ps_to_regval) should be 60 and not 200. Linux has KSZ9031_PS_TO_REG defined to be 60 as well. 60 is the correct divisor because the 4-bit skew values are defined from 0x0000(-420ps) to 0xffff(480ps), increments of 60. For example, a DTS skew value of 420, represents 0ps delay, which should be 0x7. With the previous divisor of 200, it would result in 0x2, which represents a -300ps delay. With this patch, ethernet on the SoCFPGA DE0 Atlas is now able to work with 1Gb ethernet.

2016-01-28net: phy: Use 'autoneg' flag from phydevAlexandre Messier
Use the 'autoneg' flag available in phydev when checking if autoneg is in use. The previous implementation was checking directly in the PHY if autoneg was supported. Some PHYs will report that autoneg is supported, even when it is disabled. Thus it is not possible to use that bit to determine if autoneg is currently in use or not.

2016-01-28net: phy: Set ANRESTART in setup_forcedAlexandre Messier
When configuring a PHY in fixed (forced) link mode, in order for the changes to be applied, either one of these conditions must be triggered: 1- PHY is reset 2- Autoneg is restarted 3- PHY transitions from power-down to power-up Neither of these is currently done, so effectively the fixed link configuration is not applied in the PHY. Fix this by setting the Autoneg restart bit. Signed-off-by: Alexandre Messier <amessier@tycoint.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
2016-01-28net: phy: micrel: Disable B_CAST on configAlexandre Messier
Micrel PHYs KSZ8021/31 and KSZ8081 have a feature where MDIO address 0 is considered as a broadcast address; the PHY will respond even if it is not its configured (pinstrapped) address. This feature is enabled by default. The Linux kernel disables that feature at initialisation, but not before it probes the MDIO bus. This causes an issue, because a PHY at address 3 will be discovered at addresses 0 and 3, but will then only respond at address 3. Because Linux attaches the first PHY it discovers on 'eth0', it will attach the PHY from address 0, which will never answer again. Fix the issue by disabling the broadcast feature in U-Boot, before Linux is started. Signed-off-by: Alexandre Messier <amessier@tycoint.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
2016-01-28net/designware: add support of max-speed device tree propertyAlexey Brodkin
This property allows to specify fastest connection mode supported by the MAC (as opposed to features of the phy). There are situations when phy may handle faster modes than the MAC (or even it's particular implementation or even due to CPU being too slow). This property is a standard one in Linux kernel these days and some boards do already use it in their device tree descriptions.

2016-01-28net/designware: do explicit port selection for 1Gb modeAlexey Brodkin
Current implementation only sets "port select" bit for non-1Gb mode. That works fine if GMAC has just exited reset state but we may as well change connection mode in runtime. Then we'll need to reprogram GMAC for that new mode of operation and if previous mode was 10 or 100 Mb and new one is 1 Gb we'll need to reset port mode bit.

2016-01-28drivers/net/phy: introduce phy_set_supported()Alexey Brodkin

2016-01-28net: phy: genphy: Allow overwriting featuresSascha Hauer
of_set_phy_supported allows overwiting hardware capabilities of a phy with values from the devicetree. This does not work with the genphy driver though because the genphys config_init function will overwrite all values adjusted by of_set_phy_supported. Fix this by initialising the genphy features in the phy_driver struct and in config_init just limit the features to the ones the hardware can actually support. The resulting features are a subset of the devicetree specified features and the hardware features. This is a copy of the patch from Linux kernel, see http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c242a47238fa2a6a54af8a16e62b54e6e031d4bc Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
2016-01-28net: phy: ensure Gigabit features are masked off if requestedFlorian Fainelli
When a Gigabit PHY device is connected to a 10/100Mbits capable Ethernet MAC, the driver will restrict the phydev->supported modes to mask off Gigabit. If the Gigabit PHY comes out of reset with the Gigabit features set by default in MII_CTRL1000, it will keep advertising these feature, so by the time we call genphy_config_advert(), the condition on phydev->supported having the Gigabit features on is false, and we do not update MII_CTRL1000 with updated values, and we keep advertising Gigabit features, eventually configuring the PHY for Gigabit whilst the Ethernet MAC does not support that. This patches fixes the problem by ensuring that the Gigabit feature bits are always cleared in MII_CTRL1000, if the PHY happens to be a Gigabit PHY, and then, if Gigabit features are supported, setting those and updating MII_CTRL1000 accordingly. This is a copy of patch from Linux kernel, see http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5273e3a5ca94fbeb8e07d31203069220d5e682aa Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com>

By default, a port belongs to a LAG equal to the port's number. For each frame, a hash will be calculated based on Source/Destination MAC addresses, Source/Destination IP(v4/v6) addresses, Source/Destination ports. This hash will be used to select a single egress port from LAG. This also assures that frames from the same flow will always have the same egress port.
