PHY Definition
By default, the software driver only supports the following PHYs:
• National DP83848C (10/100 Mbps)
• National DP83865 (10/100/1000 Mbps)
• Marvell 88E1111 (10/100/1000 Mbps)
• Marvell 88E1145 (Quad PHY, 10/100/1000 Mbps).
You can extend the software driver to support other PHYs by defining the PHY profile using the structure
alt_tse_phy_profile
and adding it to the system using the function
alt_tse_phy_add_profile()
. For
each PHY instance, use the structure
alt_tse_system_phy_struct
to define it and the function
alt_tse_system_add_sys() to add the instance to the system.
The software driver automatically detects the PHY’s operating mode and speed if the PHY conforms to the
following specifications:
• One bit to specify duplex and two consecutive bits (the higher bit being the most significant bit) to specify
the speed in the same extended PHY specific register.
• The speed bits are set according to the convention shown in Table 11-1 .
