Currently there is a lot of inconsistency amongst Solaris NIC drivers about what is logged to the console, what is logged to syslog, and what is dropped when link status changes. The actual messages, as well as their content, varies from driver to driver.
Many people are unhappy that a "flapping link" (a link that has upper layers trying to use it, but which is disconnected) logs aggressively to the console.
The right answer is for nemo to perform the logging on behalf of GLDv3 drivers as part of the mac_link_update() function. It should only log on a status change, and only go to the logs. Further details are always available from dladm.
