net: phy: Fix verification of EEE support in phy_init_eee

2015-03-14T19:37:11+00:00

[ Upstream commit 54da5a8be3c1e924c35480eb44c6e9b275f6444e ]

phy_init_eee uses phy_find_setting(phydev->speed, phydev->duplex)
to find a valid entry in the settings array for the given speed
and duplex value. For full duplex 1000baseT, this will return
the first matching entry, which is the entry for 1000baseKX_Full.

If the phy eee does not support 1000baseKX_Full, this entry will not
match, causing phy_init_eee to fail for no good reason.

Fixes: 9a9c56cb34e6 ("net: phy: fix a bug when verify the EEE support")
Fixes: 3e7077067e80c ("phy: Expand phy speed/duplex settings array")

net: ptp: fix time stamp matching logic for VLAN packets.

2014-11-12T20:06:17+00:00

Commit ae5c6c6d "ptp: Classify ptp over ip over vlan packets" changed the
code in two drivers that matches time stamps with PTP frames, with the goal
of allowing VLAN tagged PTP packets to receive hardware time stamps.

However, that commit failed to account for the VLAN header when parsing
IPv4 packets. This patch fixes those two drivers to correctly match VLAN
tagged IPv4/UDP PTP messages with their time stamps.

This patch should also be applied to v3.17.

net: phy: Correctly handle MII ioctl which changes autonegotiation.

2014-11-11T21:21:26+00:00

When advertised capabilities are changed with mii-tool, such as:
mii-tool -A 10baseT
the existing handler has two errors.

- An actual PHY register value is provided by mii-tool, and this
  must be mapped to internal state with mii_adv_to_ethtool_adv_t().
- The PHY state machine needs to be told that autonegotiation has
  again been performed.  If not, the MAC will not be notified of
  the new link speed and duplex, resulting in a possible config
  mismatch.

net: phy: Add SGMII Configuration for Marvell 88E1145 Initialization

2014-10-28T21:00:22+00:00

Marvell phy 88E1145 configuration & initialization was missing a case
for initializing SGMII mode. This patch adds that case.

phy/micrel: KSZ8031RNL RMII clock reconfiguration bug

2014-10-14T16:41:03+00:00

Bug: Unable to send and receive Ethernet packets with Micrel PHY.

Affected devices:
KSZ8031RNL (commercial temp)
KSZ8031RNLI (industrial temp)

Description:
PHY device is correctly detected during probe.
PHY power-up default is 25MHz crystal clock input
and output 50MHz RMII clock to MAC.
Reconfiguration of PHY to input 50MHz RMII clock from MAC
causes PHY to become unresponsive if clock source is changed
after Operation Mode Strap Override (OMSO) register setup.

Cause:
Long lead times on parts where clock setup match circuit design
forces the usage of similar parts with wrong default setup.

Solution:
Swapped KSZ8031 register setup and added phy_write return code validation.

Tested with Freescale i.MX28 Fast Ethernet Controler (fec).

net/phy: micrel: Add clock support for KSZ8021/KSZ8031

2014-10-10T19:35:13+00:00

The KSZ8021 and KSZ8031 support RMII reference input clocks of 25MHz
and 50MHz. Both PHYs differ in the default frequency they expect
after reset. If this differs from the actual input clock, then
register 0x1f bit 7 must be changed.

net: phy: adjust fixed_phy_register() return value

2014-10-07T17:06:45+00:00

Adjust fixed_phy_register() to return struct phy_device *, so that
it becomes easy to use fixed PHYs without device tree support:

  phydev = fixed_phy_register(PHY_POLL, &fixed_phy_status, NULL);
  fixed_phy_set_link_update(phydev, fixed_phy_link_update);
  phy_connect_direct(netdev, phydev, handler_fn, phy_interface);

This change is a prerequisite for modifying bcmgenet driver to work
without a device tree on Broadcom's MIPS-based 7xxx platforms.
