            Bug ID: 208022
           Summary: ixgbe - unexpected "ix0: Invalid advertised speed;
                    valid modes are 0x1 through 0x7" at boot time
           Product: Base System
           Version: 10.3-BETA2

          Severity: Affects Some People

Example console messages and sysctl values

Somewhere along the line, the ixgbe driver started printing an unexpected "=
ix0:
Invalid advertised speed; valid modes are 0x1 through 0x7" at boot time as
shown in the attachment. The hardware is a retail Intel X540-T1 card at the
latest firmware revision. The two (why two?) sysctls in the attachment are =
at
their default value. The 2.8.3 driver in earlier 10.3 builds didn't do this=
, so
it is probably due to something in the 3.1.13-k import.

The message seems harmless, but should probably be fixed. Note that simply
changing the default value of one / both sysctls may not have the desired
effect - a quick look in the driver source shows a bunch of potential error
messages when trying to select the advertised speed on (for example) fiber
ports.
