Subject: [PATCH iproute2-next 2/4] bridge: colorize output and use JSON print library
Use new functions from json_print to simplify code.
Provide standard flag for colorizing output.
Note: the simple -c flag is ambiguous it could mean color or
compressvlan; it is now changed to mean color for consistency
with other iproute2 commands.
Signed-off-by: Stephen Hemminger <stephen@...workplumber.org>
