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.
