2012-06-27phy: Fix warning in get_phy_device().David S. Miller1-2/+2
drivers/net/phy/phy_device.c: In function ‘get_phy_device’: drivers/net/phy/phy_device.c:340:14: warning: ‘phy_id’ may be used uninitialized in this function [-Wmaybe-uninitialized] GCC can't see that when we return zero we always initialize phy_id and that's the only path where we use it.

2012-06-27netdev/phy: Add driver for Broadcom BCM87XX 10G Ethernet PHYsDavid Daney3-0/+244
Add a driver for BCM8706 and BCM8727 devices. These are a 10Gig PHYs which use MII_ADDR_C45 addressing. They are always 10G full duplex, so there is no autonegotiation. All we do is report link state and send interrupts when it changes. If the PHY has a device tree of_node associated with it, the "broadcom,c45-reg-init" property is used to supply register initialization values when config_init() is called.

2012-06-27netdev/phy/of: Add more methods for binding PHY devices to drivers.David Daney1-0/+7
Allow PHY drivers to supply their own device matching function (match_phy_device()), or to be matched OF compatible properties. PHYs following IEEE802.3 clause 45 have more than one device identifier constants, which breaks the default device matching code. Other 10G PHYs don't follow the standard manufacturer/device identifier register layout standards, but they do use the standard MDIO bus protocols for register access. Both of these require adjustments to the PHY driver to device matching code. If the there is an of_node associated with such a PHY, we can match it to its driver using the "compatible" properties, just as we do with certain platform devices. If the "compatible" property match fails, first check if there is a driver supplied matching function, and if not fall back to the existing identifier matching rules.

2012-06-27netdev/phy/of: Handle IEEE802.3 clause 45 Ethernet PHYs in of_mdiobus_register()David Daney1-4/+12
Define two new "compatible" values for Ethernet PHYs. "ethernet-phy-ieee802.3-c22" and "ethernet-phy-ieee802.3-c45" are used to indicate a PHY uses the corresponding protocol. If a PHY is "compatible" with "ethernet-phy-ieee802.3-c45", we indicate this so that get_phy_device() can properly probe the device. If get_phy_device() fails, it was probably due to failing the probe of the PHY identifier registers. Since we have the device tree telling us the PHY exists, go ahead and add it anyhow with a phy_id of zero. There may be a driver match based on the "compatible" property.

2012-06-27netdev/phy: Handle IEEE802.3 clause 45 Ethernet PHYsDavid Daney3-10/+99
The IEEE802.3 clause 45 MDIO bus protocol allows for directly addressing PHY registers using a 21 bit address, and is used by many 10G Ethernet PHYS. Already existing is the ability of MDIO bus drivers to use clause 45, with the MII_ADDR_C45 flag. Here we add struct phy_c45_device_ids to hold the device identifier registers present in clause 45. struct phy_device gets a couple of new fields: c45_ids to hold the identifiers and is_c45 to signal that it is clause 45. get_phy_device() gets a new parameter is_c45 to indicate that the PHY device should use the clause 45 protocol, and its callers are adjusted to pass false. The follow-on patch to of_mdio.c will pass true where appropriate. EXPORT phy_device_create() so that the follow-on patch to of_mdio.c can use it to create phy devices for PHYs, that have non-standard device identifier registers, based on the device tree bindings.

2012-06-27net: fec: reset phy after pinctrl setupShawn Guo1-2/+2
In case that bootloader or platform initialization does not set up fec pins, the fec_reset_phy will not be able to succeed, because fec_reset_phy is currently called before devm_pinctrl_get_select_default.

2012-06-27cnic: Fix occasional NULL pointer dereference during reboot.Michael Chan1-2/+7
We register with bnx2x before we allocate ctx_tbl structure, so it is possible for bnx2x to call cnic_ctl before the structure is allocated. This can sometimes cause NULL pointer dereference of cp->ctx_tbl. We fix this by adding simple checking for valid state before proceeding. The cnic_ctl call is RCU protected so we don't have to deal with race conditions. Because of the additional checking, we need to finish the shutdown before clearing the CNIC_UP flag.

2012-06-22r8169: RxConfig hack for the 8168evl.françois romieu1-0/+1
The 8168evl (RTL_GIGA_MAC_VER_34) based Gigabyte GA-990FXA motherboards are very prone to NETDEV watchdog problems without this change. See https://bugzilla.kernel.org/show_bug.cgi?id=42899 for instance. I don't know why it *works*. It's depressingly effective though. For the record: - the problem may go along IOMMU (AMD-Vi) errors but it really looks like a red herring. - the patch sets the RX_MULTI_EN bit. If the 8168c doc is any guide, the chipset now fetches several Rx descriptors at a time. - long ago the driver ignored the RX_MULTI_EN bit. e542a2269f232d61270ceddd42b73a4348dee2bb changed the RxConfig settings. Whatever the problem it's now labeled a regression. - Realtek's own driver can identify two different 8168evl devices (CFG_METHOD_16 and CFG_METHOD_17) where the r8169 driver only sees one. It sucks.
