The descriptor table size is equal to its alignment and set when configuring the HW IP through VHDL generics. This SW patch simply probes the HW how large the RX/TX descriptor tables are and adjusts accordingly. The number of descriptors actual used are controlled by other settings (rxDescs and txDescs) controlled by the user.
A non Driver Manager GRETH driver is located in libchip/network/greth.c. This version requires the driver manager. network_interface_add is used to assign IP/NETMASK and MAC address to GRETH interfaces dynamically according to in which order devices are registered. The function takes the settings from the user defined interface_configs[] array, defined in the project configuration.
