82599 10 GbE Controller
58 82599 LAN Port #1 SFI Link Instability
Problem:
If the PCIe Function #0 is moved to D3 state, it might affect the link of Port #1. For example, when the
Windows driver is disabled for this function.
This issue might happen only under the following conditions:
• Both ports are configured to SFI Link mode.
• Manageability is not enabled.
• APM (WoL) is not enabled.
• Port #0 has no link before disabled.
Implication:
Port #1 link instability.
Workaround:
Set Core Clocks Gate Disable bit in EEPROM Control Word 2.
Status: B0=Yes; NoFix
Fixed in EEPROM Dev Starter revision 4.25 or later.
59 NC-SI: Get NC-SI Pass-through Statistics Response
Might Contain Incorrect Packet Counts
Problem:
The 82599 maintains packet counters that are used in the Get NC-SI Pass-through Statistics Response.
These counters are halted during PCIe reset.
Implication:
If a PCIe reset has occurred since the previous Get NC-SI Pass-through Statistics Response, the packet
count values could be lower than the actual packet counts.
Workaround:
The packet counts in the Get NC-SI Pass-through Statistics Response may be used for debug purposes,
but they should not be used for maintaining reliable statistics.
Status: B0=Yes; NoFix
