[OmniOS-discuss] Intel Corporation 82599ES 10-Gigabit not working since upgrade to r151020

[Dale Ghent]

The Intel ixgbe driver (and igb/e1000g driver for the 1Gb NICs as well) comes in two parts: The “Intel Common Code” - a library that’s maintained by Intel and provides the core functions for configuring and operating an Intel NIC, and the OS-specific wrapper code that uses it and provides all the OS-specific logic to interface between the ICC and the OS’s own management and network APIs.

When it comes to SFP/SFFP copper and optical parts, Intel tests the ICC using a specific set of these from specific vendors. The ICC code interrogates the SFP module for its make and model, and if it’s not on their list of tested parts, you see the warning that you saw. Unless it’s overridden (in our case, by adding the line in ixgbe.conf) the ICC will refuse to progress during the interface attach phase, or during the setup phase if a module was replaced after boot.

Intel maintains a list of these makes and models for each card. For example, here’s the list for the X520 (aka 82599)
