Subject: [PATCH net-next v3 0/8] TXGBE PHYLINK support

Implement I2C, SFP, GPIO and PHYLINK to setup TXGBE link and switch link
rate based on optical module information.

Because our I2C and PCS are based on Synopsys Designware IP-core, extend
the i2c-designware and pcs-xpcs driver to realize our functions.

v2 -> v3:
- delete own I2C bus master driver, support it in i2c-designware
- delete own PCS functions, remove pma configuration and 1000BASE-X mode
- add basic function for 10GBASE-R interface in pcs-xpcs
- add helper to get txgbe pointer from netdev

v1 -> v2:
- add comments to indicate GPIO lines
- add I2C write operation support
- modify GPIO direction functions
- rename functions related to PHY interface
- add condition on interface changing to re-config PCS
- add to set advertise and fix to get status for 1000BASE-X mode
- other redundant codes remove

Jiawen Wu (8):
