    net: hns3: refactor dump tm map of debugfs · 7679f28e
    Guangbin Huang authored
    Currently, the debugfs command for tm map is implemented by
    "echo xxxx > cmd", and record the information in dmesg. It's
    unnecessary and heavy. To improve it, create a single file
    "tm_map" for it, and query it by command "cat tm_map",
    return the result to userspace, rather than record in dmesg.
    
    As user can't specify queue id in cat command, driver will return info
    of all queue id.
    
    The display style is below:
    $ cat tm_map
    queue_id   qset_id   pri_id   tc_id
    0000         0000      00       00
