Wake On LAN
The GbE does not support preservation of Magic Packets for Wake On LAN. Additionally,
the storage of other packets received after a qualifying wake event is not supported
until the GbE has been returned to a D0a state. If the GbE was in D3 then it must be
specifically moved to D0 by the IA software writing to the Power Capability register or
Reset must be cycled and the GbE re-initialized. Software intervention is required to
move the GbE to D0a and restart packet receive processing.
Feature List
The following is a list of GbE MAC features:
• Compliant with the 1000 Mbps Ethernet/802.3z specification.
• Half-duplex MII operation.
• Full-duplex operation at all MII and GMII speeds.
• Programmable system memory receive buffers (256B to 16KB).
• 64B cache-line size.
• 64KB RX/TX packet buffer (defaulted to 48 KB RX and 16 KB TX, but configurable).
• Descriptor ring management hardware for TX packet buffer.
• Support for little-endian or big-endian byte ordering.
• Flow Control Support: send/receive PAUSE frames & receive FIFO thresholds.
• Statistics for Local Management and Software Optimization.
• A mechanism for delaying/reducing transmit interrupts.
• Functional and Error interrupt signals.
• Software-controlled reset bit.
• Frame formats supported by the EP80579’s GbE include:
— Ethernet 802.3
— IEEE 802.1q VLAN (Ethernet 802.3ac)
— Ethernet Type 2
— Ethernet SNAP
— IPv4 headers with options
— IPv6 headers with IP option next headers.
— IPv6 packet tunneled in IPv4.
— TCP with options.
— UDP with options.
• Multi-speed operation: 10/100/1000 Mbps.
• All local memories and buffers are protected.
