Ethernet Controller I210 —Introduction

1.6 I210 and I211 Options

Table 1-10 lists the main differences between features supported by the I210 and I211.

1.7 Overview of Changes Compared to the I350

The following section describes the modifications designed in the I210 compared to the I350.

1.7.1 Network Interface

1.7.1.1 Energy Efficient Ethernet (IEEE802.3AZ)

The I210 supports negotiation and link transition to a Low Power Idle (LPI) state as defined in the

IEEE802.3az (EEE) standard. Energy Efficient Ethernet (EEE) is supported only in the internal copper

PHY mode and for the following technologies:

• 1000BASE-T

• 100BASE-TX

EEE enables reduction of the I210 power consumption as a function of link utilization. In addition, the

I210 enables overall system power reduction as a function of link utilization by reporting increased

latency tolerance values via PCIe LTR messages when link is in the LPI state. For more information,

refer to Section 3.7.7.

LAN disable functionality (equivalent to Static device off

functionality in the I210/I211)

PCIe function disable Y Y Y Y

Dynamic device off Y

EEE YYYN

DMA coalescing Y N Y N

OBFF/PE_WAKE_N Y

NNN

1. Feature not functional if enabled together with dynamic device off.

2. Feature not functional if enabled together with static device off (such as LAN disable).

3. Disabled by default in Flash due to the lack of OBFF enabled platforms at initial release.
