phy: fix EEE checks inside the phy_init_eee.

2014-08-27T23:29:39+00:00

According to the Std 802.3az if the EEE Adv (Reg 7.60), Link partner ability
(Reg 7.61) and EEE capability (Register 3.20) bits return 0 this  means no EEE
is supported. So this patch fixes the checks inside the phy_init_eee function.

net: libphy: Add phy specific function to access mmd phy registers

2014-07-31T03:00:21+00:00

libphy was originally written assuming all phy devices support clause 45
access extensions to the mmd registers through the indirection registers
located within the first 16 phy registers. This assumption is not true
in all cases, and one specific example is the Micrel ksz9021 10/100/1000
Mbps phy. Using the stmmac driver, accessing the mmd registers to query
and configure energy efficient Ethernet (EEE) features yielded unexpected
behavior.

This patch adds mmd access functions to the phy driver that can be
overriden by the phy specific driver if the phy does not support this
mechanism or uses it's own non-standard access mechanism. By default,
the IEEE Compatible clause 45 access mechanism described in clause 22
is used. With this patch, EEE query/configure functions as expected
using the stmmac and the Micrel ksz9021 phy.

phy: Expand phy speed/duplex settings array

2014-07-15T23:30:04+00:00

Expand the phy speed/duplex settings array to support more
than just baseT features. This change adds entries to support
the following additional speed/duplex/media types:
	SUPPORTED_10000baseKR_Full
	SUPPORTED_10000baseKX4_Full
	SUPPORTED_2500baseX_Full
	SUPPORTED_1000baseKX_Full

Additionally, it changes the 10GbE baseT entry from using the
hardcoded value 10000 to the SPEED_10000 define.

net: phylib: add link_change_notify callback to phy device

2014-06-21T22:50:00+00:00

Add a notify callback to inform phy drivers when the core is about to
do its link adjustment. No change for drivers that do not implement
this callback.

net: phy: resume phydev when going to RESUMING

2014-05-16T19:17:58+00:00

With commit be9dad1f9f26604fb ("net: phy: suspend phydev when going
to HALTED"), an unused PHY device will be put in a low-power mode
using BMCR_PDOWN. Some Ethernet drivers might be calling phy_start()
and phy_stop() from ndo_open and ndo_close() respectively, while
calling phy_connect() and phy_disconnect() from probe and remove.
In such a case, the PHY will be powered down during the phy_stop()
call, but will fail to be powered up in phy_start().
This patch fixes this scenario.

net phy: Check for aneg completion before setting state to PHY_RUNNING

2014-05-02T19:50:57+00:00

phy_state_machine should check whether auto-negotiatin is completed
before changing phydev->state from PHY_NOLINK to PHY_RUNNING. If
auto-negotiation is not completed phydev->state should be set to
PHY_AN.

phy: fix compiler array bounds warning on settings[]

2014-03-06T21:07:25+00:00

With -Werror=array-bounds, gcc v4.7.x warns that in phy_find_valid(), the
settings[] "array subscript is above array bounds", I think because idx is
a signed integer and if the caller supplied idx < 0, we pass the guard but
still reference out of bounds.

Fix this by making idx unsigned here and elsewhere.
