bcm56xxd provides tuning (also known as precondtioning) for 100G modules. bcm56xxd will issue log messages of the form: bs_module_do_precond :No preconditioning provided for module on port X.x.


None. This message is informational only and is indicating that a module was found for which no tuning is required.


This message will be observed when optics modules are discovered at startup or removed/inserted.



Fix Information

The sense of the message should change so that it is emitted only when tuning is provided for a module. It also needs to be info level or less.
