From: David Ertman <redacted> Valid values for InterruptThrottleRate are 10-100000, or one of 0, 1, 3, 4. '2' is not valid. This is a legacy from the branching from the e1000 driver code that e1000e was based from. Prior to this patch, if the e1000e driver was loaded with a forced invalid InterruptThrottleRate of '2', then no throttle rate would be set and no error message generated. Now, a message will be generated that an invalid value was used and the value for InterruptThrottleRate will be set to the default value.
