From: Mathias Nyman commit cdc77c82a8286b1181b81b6e5ef60c8e83ded7bc upstream. The current implemenentation restart the sent pattern for each entry in the sg list. The receiving end expects a continuous pattern, and test will fail unless scatterilst entries happen to be aligned with the pattern Fix this by calculating the pattern byte based on total sent size instead of just the current sg entry.
