This adds support for json output on tc u32.
- The first patch is replacing with proper json functions in `u32_print_opt()`
- The second patch is fixing the json support in u32 `print_raw()`, `print_ipv4()`
and `print_ipv6()`
Wen Liang (2):
tc: u32: add support for json output
tc: u32: add json support in `print_raw`, `print_ipv4`, `print_ipv6`

Currently u32 filter output does not support json. This commit uses
proper json functions to add support for it.

Use print_nl() which handles oneline mode rather than explicit newline print
