Subject: [PATCH net-next v5 0/6] dsa: lan9303: Move to PHYLINK

This patch series moves the lan9303 driver to use the phylink
api away from phylib.

Migrating to phylink means removing the .adjust_link api. The
functionality from the adjust_link is moved to the phylink_mac_link_up
api.  The code being removed only affected the cpu port.  The other
ports on the LAN9303 do not need anything from the phylink_mac_link_up api.

Patches:
 0001 - Whitespace only change aligning the dsa_switch_ops members.
	No code changes.
 0002 - Moves the Turbo bit initialization out of the adjust_link api and
	places it in a driver initialization execution path. It only needs
	to be initialized once, it is never changed, and it is not a
	per-port flag.
 0003 - Adds exception handling logic in the extremely unlikely event that
	the read of the device fails.
 0004 - Performance optimization that skips a slow register write if there is
	no need to perform it.
 0005 - Change the macro used to identify the cpu port as phydev will be NULL
	when this logic is moved into phylink_mac_link_up.
 0006 - Removes adjust_link and begins using the phylink dsa_switch_ops apis.

---
v3->v5:
  - Created prep patches to better show how things migrate.
  - cleaned up comments.
v3->v4:
  - Addressed whitespace issues as a separate patch.
  - Removed port_max_mtu api patch as it is unrelated to phylink migration.
  - Reworked the implementation to preserve the adjust_link functionality
    by including it in the phylink_mac_link_up api.
v2->v3:
  Added back in disabling Turbo Mode on the CPU MII interface.
  Removed the unnecessary clearing of the phyvsupported interfaces.
v1->v2:
  corrected the reported mtu size, removing ETH_HLEN and ETH_FCS_LEN
