82599 10 GbE Controller—Errata

44 Header Splitting Can Cause Unpredictable Behavior

Problem:

Header Splitting mode (SRRCTL.DESCTYPE=010b or 101b and PSRTYPE[11:0]≠0) might cause

unpredictable behavior and should not be used.

Implication:

Unpredictable behavior.

Workaround:

Header Splitting should not be enabled. Starting with Intel

driver Release 16.0, Header Splitting

cannot be enabled.

Status: B0=Yes; NoFix

45 PCIe Compliance Pattern Is not Transmitted When

Connected to a x4/x2/x1 Slot

Problem:

If the PCIe compliance pattern is activated by setting the Enter Compliance bit in the Link Control 2

connected to a x4, x2 or x1 slot, the unconnected lanes falsely cause a premature exit from the

compliance state and the pattern is not transmitted.

If a passive test load is applied on all lanes, the 82599 goes to a compliance state and transmits the

pattern accordingly, regardless of the internal lane width configuration.

Implication:

A PCIe compliance pattern cannot be transmitted if the 82599 is connected to an x4 or narrower PCIe

slot.

Workaround:

None.

Status: B0=Yes; NoFix
