Support for Faraday's FTGMAC100 Gigabit SoC Ethernet

CONFIG_FTGMAC100_EGIGA

Define this to use GE link update with gigabit PHY.
|

|
Define this if FTGMAC100 is connected to gigabit PHY.
|
||||||
|
If your system has 10/100 PHY only, it might not occur
|
||||||
|
wrong behavior. Because PHY usually return timeout or
|
||||||
|
useless data when polling gigabit status and gigabit
|
||||||
|
control registers. This behavior won't affect the
|

|
correctnessof 10/100 link speed update.
