From: Salil Mehta
Date: Sun Dec 02 2018 - 18:11:40 EST
From: liuzhongzhu <liuzhongzhu@xxxxxxxxxx>
This patch prints queue map information.
debugfs command:
echo dump queue map > cmd
Sample Command:
root@(none)# echo queue map > cmd
local queue id | global queue id | vector id
0 32 769
1 33 770
2 34 771
3 35 772
4 36 773
5 37 774
