28 Re-Enabling a Port Using the Rising Edge of
LAN_DIS_N Requires a LAN_PWR_GOOD Reset
Problem:
To re-enable a port using the rising edge of LAN_DIS_N (after it was disabled through the pin) it is
required to go through a LAN_PWR_GOOD reset. PERST# (PCIe reset) cannot be used to re-enable a
port.
Implication:
This limitation requires a cold boot in order for the LAN_DIS_N rise to take effect.
Workaround:
Reset the 82599 using LAN_PWR_GOOD (cold reboot).
Status: B0=Yes; NoFix
29 BMC Receives Non-MACSec Packets from the LAN
Without an Indication Regarding to Received
Packet Type (With/Without MACSec Header)
Problem:
When operating in MACSec strict mode, all non-received packets pass the MACSec logic and are
forwarded to the BMC. In NC-SI mode, the BMC doesn't get the packet descriptor so it can't know if the
packet is a trusted packet that was processed by the MACSec logic or non-trusted packet that skipped
over the MACSec logic (this is indicated in the SECP bit in the descriptor status).
Implication:
NC-SI BMC can't differentiate between MACSec and non-MACSec packets.
Workaround:
None.
Status: B0=Yes; NoFix
30 NC-SI: Additional Multicast Packets May Be
Forwarded to the BMC
Problem:
If the BMC enables multicast filtering for IPv6 neighbor advertisement and/or IPv6 router
advertisement, additional multicast packets are forwarded to the BMC. The additional packets
forwarded are:
• Packets with ICMPv6 header message type: 135,137.
• IPv6 neighbor advertisement.
• IPv6 router advertisement.
