[PATCH net-next 0/1] Add genphy_c45_config_aneg() function to phy-c45.c

[Marco Hartmann]

Currently, using a Clause 45 Phy with the "Generic Clause 45 PHY"
driver leads to a warning, similar to the one below, as soon as the interface
is brought up.


  ------------[ cut here ]------------
  WARNING: CPU: 2 PID: 146 at drivers/net/phy/phy.c:736 phy_error+0x2c/0x64
  Modules linked in: fec
  CPU: 2 PID: 146 Comm: kworker/2:1 Not tainted 5.3.0-rc3-NETNEXT-00816-g48e924c73178 #20
  Hardware name: Freescale i.MX6 Quad/DualLite (Device Tree)
  Workqueue: events_power_efficient phy_state_machine
  Backtrace:

This happens, because the Genphy driver does not provide a config_aneg() func,
so that phy_start_aneg() ultimately fails such that phy_error() is called,
producing the above warning.

This patch adds the function genphy_c45_config_aneg(), which allows
phy_start_aneg() to work correctly for C45 phys.
