Patch #1 adds a new helper for finding a name of a given dsfield value. This is useful for APP DSCP-to-priority rules, which can use human-readable DSCP names. Patches #2, #3 and #4 extend existing interfaces for, respectively, parsing of the X:Y mappings, for setting a DCB object, and for getting a DCB object. In patch #5, support for the command line argument -N / --Numeric is added. The APP tool later uses it to decide whether to format DSCP values as human-readable strings or as plain numbers. Patches #6 and #7 add the subtools themselves and their man pages. v2: - Two patches dropped and sent to iproute2 branch as "dcb: Fixes". This patch set now depends on that one. - Patch #5: - Make it -N / --Numeric instead of -n / --no-nice-names - Rename the flag from no_nice_names to numeric as well - Patch #6: - Adjust to s/no_nice_names/numeric/ from another patch.
