Subject: [PATCH V2 net-next 0/2] net: hns3: updates for -next

This patchset adds dump tm info of nodes, priority and qset in debugfs.
Three debugfs files tm_nodes, tm_priority and tm_qset are created in
new tm directory, and use cat command to dump their info, for examples:

$ cat tm_nodes
       BASE_ID  MAX_NUM
PG         0         8
PRI        0         8
QSET       0         8
QUEUE      0      1024
