82599 10 GbE Controller—Errata

51 LEDs Cannot Be Configured to Blink in LED_ON

Mode

Problem:

When the LEDx_Mode field of a specific LED is set to 1110b in the LEDCTL register (0x00200), the

respective LED is in LED_ON mode. This LED should be always asserted when the mode is set to

LED_ON. The LED should also blink based on the LEDx_BLINK setting; however, due to a device

limitation, the LED does not blink regardless of the LEDx_BLINK value.

Implication:

LEDs cannot be configured to blink in LED_ON mode.

Workaround:

The software driver should switch between LED_ON and LED_OFF mode to make the LED blink.

Status: B0=Yes; NoFix

52 NC-SI: Get NC-SI Pass-Through Statistics

Response Format

Problem:

The NC-SI Specification, version 1.0.0a defines the Pass-through Tx Packets counter contained in the

Get NC-SI Pass-through Statistics Response Packet to be an 8-byte field. The 82599 provides this

counter as a 4-byte field.

Implication:

A BMC that uses the Get NC-SI Pass-through Statistics command and expects the response format as

described in the NC-SI Specification will not parse the response as intended by the 82599 and will

obtain inaccurate statistics.

Workaround:

The BMC can account for the different format provided by the 82599 and parse the response

accordingly.

Status: B0=Yes; NoFix

53 Flow Director Filters Configuration Issue

Problem:

Before an 82599 receive path enable, the default value of both RXCTRL.RXEN and SECRXCTL.RX_DIS is

zero. If the flow director filters are configured in this state, the receive data buffer might not be

configured correctly.

Implication:

Receive hang.
