Error description
ECH_MAIN_CHAN_FAIL will be observed in the error log at boot time when mlxentdd is the driver for the real adapters used by the etherchannel. Note that the ECH_MAIN_CHAN_FAIL at boot time may actually be valid. When the etherchannel is configured, it sets a call back function in the real adapter's driver. The call to set the call back function can return three values: an error, an indicating that the call worked and the state of the link is presently known, and an indication that the call worked but the state of the link is currently not known (e.g. when the real adapter is first opened). The mlxentdd was not utilizing the third alternative. If the state of the link is known and the link is currently down, then the user will see the ECH_MAIN_CHAN_FAIL error message even if the link becomes up shortly after the configuration process.
Local fix
Problem summary
ECH_MAIN_CHAN_FAIL may be observed in the error log at boot time for Etherchannel configured on devices using mlxentdd driver.
Problem conclusion
Code changed to handle the condition where the link state is not known when Etherchannel gets configured.
