And to describe what has changed >From v1 either in individual patches below the '--' or in the cover letter. So can you please describe what changed from previous submission in case it's not obvious to reviewers? For example: [PATCH v2 0/3] Add get/set ethernet address functions and ACPI MAC address pass through functionality to cdc_ncm driver Changes from v1 to v 2: * Changed foo to bar
