[PATCH net-next v4 0/3] Add phylib support to smsc95xx

[Andre Edich <andre.edich@microchip.com>]

To allow to probe external PHY drivers, this patch series adds use of
phylib to the smsc95xx driver.

Changes in v4:
- Removed useless inline type qualifier.

Changes in v3:
- Moved all MDI-X functionality to the corresponding phy driver;
- Removed field internal_phy from a struct smsc95xx_priv;
- Initialized field is_internal of a struct phy_device;
- Kconfig: Added selection of PHYLIB and SMSC_PHY for USB_NET_SMSC95XX.

Changes in v2:
- Moved 'net' patches from here to the separate patch series;
- Removed redundant call of the phy_start_aneg after phy_start;
- Removed netif_dbg tracing "speed, duplex, lcladv, and rmtadv";
- mdiobus: added dependency from the usbnet device;
- Moved making of the MII address from 'phy_id' and 'idx' into the
  function mii_address;
- Moved direct MDIO accesses under condition 'if (pdata->internal_phy)',
  as they only need for the internal PHY;
- To be sure, that this set of patches is git-bisectable, tested each
  sub-set of patches to be functional for both, internal and external
  PHYs, including suspend/resume test for the 'devices'
  (5.7.8-1-ARCH, Raspberry Pi 3 Model B).

Andre Edich (3):
  smsc95xx: remove redundant function arguments
  smsc95xx: use usbnet->driver_priv
  smsc95xx: add phylib support
