2021-04-13ixgbe: Support external GBE SerDes PHY BCM54616sJostar Yang1-0/+3
The Broadcom PHY is used in switches, so add the ID, and hook it up. This upstreams the Linux kernel patch from the network operating system SONiC from February 2020 [1].

2020-10-18ixgbe: fix probing of multi-port devices with one MDIOJakub Kicinski1-9/+14
Ian reports that after upgrade from v5.8.14 to v5.9 only one of his 4 ixgbe netdevs appear in the system. Quoting the comment on ixgbe_x550em_a_has_mii(): * Returns true if hw points to lowest numbered PCI B:D.F x550_em_a device in * the SoC. There are up to 4 MACs sharing a single MDIO bus on the x550em_a, * but we only want to register one MDIO bus. This matches the symptoms, since the return value from ixgbe_mii_bus_init() is no longer ignored we need to handle the higher ports of x550em without an error.

2020-09-25intel-ethernet: clean up W=1 warnings in kdocJesse Brandeburg1-4/+4
This takes care of all of the trivial W=1 fixes in the Intel Ethernet drivers, which allows developers and maintainers to build more of the networking tree with more complete warning checks. There are three classes of kdoc warnings fixed: - cannot understand function prototype: 'x' - Excess function parameter 'x' description in 'y' - Function parameter or member 'x' not described in 'y' All of the changes were trivial comment updates on function headers. Inspired by Lee Jones' series of wireless work to do the same.

2020-06-30net: ethernet: ixgbe: don't call devm_mdiobus_free()Bartosz Golaszewski1-11/+3
The idea behind devres is that the release callbacks are called if probe fails. As we now check the return value of ixgbe_mii_bus_init(), we can drop the call devm_mdiobus_free() in error path as the release callback will be called automatically.

2019-03-26ixgbe: fix mdio bus registrationIvan Vecera1-7/+9
The ixgbe ignores errors returned from mdiobus_register() and leaves adapter->mii_bus non-NULL and MDIO bus state as MDIOBUS_ALLOCATED.

Most dsa devices expect a 'struct mii_bus' pointer to talk to switches via the MII interface. While this works for dsa devices, it will not work safely with Linux PHYs in all configurations since the firmware of the ixgbe device may be polling some PHY addresses in the background.

2016-11-04ixgbe: use link instead of I2C combined abstractionEmil Tantilov1-64/+4
Introduce ixgbe_link_operations struct with the following changes: read_i2c_combined => read_link read_i2c_combined_unlocked => read_link_unlocked write_i2c_combined => write_link write_i2c_combined_unlocked => write_link_unlocked This will allow X550EM_a to override these methods for MDIO access while X550EM_x provides methods to use I2C combined access. This also adds a new structure, ixgbe_link_info, to hold information about the link. Initially this is just method pointers and a bus address. The functions involved in combined I2C accesses were moved from ixgbe_phy.c to ixgbe_x550.c. The underlying functions that carry out the combined I2C accesses were left in ixgbe_phy.c because they share some functions with other I2C methods. v2 - set hw->link.ops in probe. v3 - check ii->link_ops before setting it since we don't have it for all devices.

2015-09-01ixgbe: Remove second instance of lan_id variableDon Skidmore1-3/+1
This patch removes the redundant lan_id in the phy struct and uses the bus version. Both variables exist and intend to represent the STATUS register LAN_ID field. However, phy.lan_id is not bit shifted so the phy.lan_id = 0x0 for LAN Id 0 and phy.lan_id = 0x4 for LAN Id 1. Where bus.lan_id is bit shifted so bus.lan_id = 0x0 for LAN Id 0 and bus.lan_id = 0x1 for LAN Id 1. There seems no need for the additional lan_id variable and this should make the code less confusing.
