TC is another tool that has a number of such commands, and functions to support them: get_size(), get_rate/64(), s/print_size() and s/print_rate(). In this patchset, these functions are moved from TC to lib/ for possible reuse and modernized. s/print_rate() has a hidden parameter of a global variable use_iec, which made the conversion non-trivial. The parameter was made explicit, print_rate() converted to a mostly json_print-like function, and sprint_rate() retired in favor of the new print_rate. Patches #1 and #2 deal with this. The intention was to treat s/print_size() similarly, but unfortunately two use cases of sprint_size() cannot be converted to a json_print-like print_size(), and the function sprint_size() had to remain as a discouraged backdoor to print_size(). This is done in patch #3. Patch #4 then improves the code of sprint_size() a little bit. Patch #5 fixes a buglet in formatting small rates in IEC mode. Patches #6 and #7 handle a routine movement of, respectively, get_rate/64() and get_size() from tc to lib. This patchset does not actually add any new uses of these functions. A follow-up patchset will add subtools for management of DCB buffer and DCB maxrate objects that will make use of them. v2: - Patch #2: - Adapt q_mqprio.c patch, the file changed since v1. - Patch #4: - This patch is new. It addresses a request from Stephen Hemminger to clean up the sprint_size() function.
