net: hns3: refactor dump qos pri map of debugfs
Currently, user gets priority map by implementing debugfs command
"echo dump qos pri map > cmd", this command will dump info in dmesg.
It's unnecessary and heavy.
To optimize it, create a single file "qos_pri_map" in tm directory
and use cat command to get info. It will return info to userspace,
rather than record in dmesg.
The display style is below:
$ cat qos_pri_map
vlan_to_pri: 0
PRI TC
0 0
1 1
2 2
3 3
4 0
5 1
6 2
