Local fix
Problem summary
The DMA_ERR added to setup tce, when the adapter device driver requesting more DMA space than is available, the common recovery for this is to decrease the size of the DMA request and try again. During this failure , we are logging error with error type UNKN. This couldn't tell if the DMA_ERR failure is a real issue or a temporary DMA mapping operation on a transmit packet message. This will not provide enough information to determine the severity of the error.
Problem conclusion
Changing error type from "unknown" to "informational"
Temporary fix
