[PATCH iproute2-next v4 2/6] json_print: Add print_tv()
From: Petr Machata <petrm@nvidia.com>
Date: 2021-03-17 12:56:05
Subsystem:
library code, the rest · Maintainers:
Andrew Morton, Linus Torvalds
Add a helper to dump a timeval. Print by first converting to double and
then dispatching to print_color_float().
Signed-off-by: Petr Machata <petrm@nvidia.com>

Notes:
v4:
- Make print_tv() take a const*.
