net/mlx5: DR, Add support for dumping steering info
Extend mlx5 debugfs support to present Software Steering resources:
dr_domain including it's tables, matchers and rules.
The interface is read-only. While dump is being presented, new steering
rules cannot be inserted/deleted.
The steering information is dumped in the CSV form with the following
format:
<object_type>,<object_ID>, <object_info>,...,<object_info>
This data can be read at the following path:
/sys/kernel/debug/mlx5/<BDF>/steering/fdb/<domain_handle>
Example:
# cat /sys/kernel/debug/mlx5/0000:82:00.0/steering/fdb/dmn_000018644
3100,0x55caa4621c50,0xee802,4,65533
3101,0x55caa4621c50,0xe0100008
Changes in V2:
- Reduce temp hex buffer size and avoid unnecessary memset
- Use bin2hex() instead of DIY loop
- Don't check debugfs functions return values
