This driver supports the Faraday's FTGMAC100 Gigabit SoC
Ethernet controller that can be found on Aspeed SoCs (which
include NCSI).
It is fully compliant with IEEE 802.3 specification for
10/100 Mbps Ethernet and IEEE 802.3z specification for 1000
Mbps Ethernet and includes Reduced Media Independent
Interface (RMII) and Reduced Gigabit Media Independent
Interface (RGMII) interfaces. It adopts an AHB bus interface
and integrates a link list DMA engine with direct M-Bus
accesses for transmitting and receiving packets. It has
independent TX/RX fifos, supports half and full duplex (1000
Mbps mode only supports full duplex), flow control for full
duplex and backpressure for half duplex.
The FTGMAC100 also implements IP, TCP, UDP checksum offloads
and supports IEEE 802.1Q VLAN tag insertion and removal. It
offers high-priority transmit queue for QoS and CoS
applications.
