RTL8111F-CG原装 以太网芯片 的描述：

The  Realtek  RTL8111F-CG  Gigabit  Ethernet  controller  combines  a  triple-speed  IEEE  802.3  compliant  Media Access Controller (MAC) with a triple-speed Ethernet transceiver, PCI Express bus controller, and embedded  memory.  With  state-of-the-art  DSP  technology  and  mixed-mode  signal  technology,  the  RTL8111F  offers  high-speed  transmission  over  CAT  5 UTP cable or CAT 3 UTP (10Mbps only) cable. Functions  such  as  Crossover  Detection  and  Auto-Correction,  polarity  correction,  adaptive  equalization,  cross-talk  cancellation,  echo  cancellation,  timing  recovery,  and  error  correction  are  implemented  to  provide robust transmission and reception capability at high speeds.

The  RTL8111F  supports  the  PCI  Express  1.1  bus  interface  for  host  communications  with  power  management, and is compliant with the IEEE 802.3u specification for 10/100Mbps Ethernet and the IEEE 802.3ab  specification  for  1000Mbps  Ethernet.  

It  also  supports  an  auxiliary  power  auto-detect  function,  and  will  auto-configure  related  bits  of  the  PCI  power  management  registers  in  PCI  configuration  space.  The  RTL8111F  features  embedded  One-Time-Programmable  (OTP)  memory  to  replace  the  external  EEPROM (93C46/93C56/93C66).

Advanced   Configuration   Power   management   Interface   (ACPI)—power   management   for   modern   operating  systems  that  are  capable  of  Operating  System-directed  Power  Management  (OSPM)—is  supported  to  achieve  the  most  efficient  power  management  possible.  

PCI  MSI  (Message  Signaled  Interrupt) and MSI-X are also supported. In addition to the ACPI feature, remote wake-up (including AMD Magic Packet and Microsoft Wake-up frame)  is  supported  in  both  ACPI  and  APM  (Advanced  Power  Management)  environments.  To  support  WOL from a deep power down state (e.g., D3cold, i.e., main power is off and only auxiliary exists), the auxiliary power source must be able to provide the needed power for the RTL8111F.

The  RTL8111F  supports  Protocol  offload.  It  offloads  some  of  the  most  common  protocols  to  NIC  hardware  in  order  to  prevent  spurious  wake  up  and  further  reduce  power  consumption.

 The  RTL8111F  can offload ARP (IPv4) and NS (IPv6) protocols while in the D3 power saving state.
