Errata—Intel
®
82599 10 GbE Controller
Implication:
Additional packets might be forwarded to the BMC.
Workaround:
BMC should filter the different multicast packets.
Status: B0=Yes; NoFix
31 SMBus: Unread Packets Received on One Port May
Cause Loss of Ability to Receive on Other Port
Problem:
The device’s two ports share an internal memory. When packets are received by one of the ports and
not read by the BMC, they are stored in the shared memory. When this memory fills up, no more
packets may be received from either ports.
Implication:
Loss of packets. The BMC should be aware of the above behavior.
Workaround:
Do the following:
1. Make use of a SMBus alert timeout mechanism.
2. Momentarily disable receives by the other port.
Status: B0=Yes; NoFix
32 NC-SI: Packet Loss When the BMC Sends Packets
to Both Ports and One Port Has Its Link Down
Problem:
NC-SI Rx (BMC-to-LAN) FIFO is shared between both ports. When one of the LAN port’s Tx buffer is
congested because of link failure or flow control, the NC-SI Rx FIFO gets congested and as a result the
packets for the second port also gets dropped and are not sent to the LAN.
Implication:
Loss of packets. The BMC should be aware of the problem.
Workaround:
The BMC should monitor the link status and stop sending packets to a specific port if link is down.
Status: B0=Yes; NoFix
