In order to trace the relation of IDs, we add this debugfs entry to make
them clear.
The output looks like:
map:
mac_id: 07 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
addr_cam: 07 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
bssid_cam: 01 00 00 00 00 00 00 00
sec_cam: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
VIF [0] 94:08:53:8e:ef:21
bssid_cam_idx=0
addr_cam_idx=0
-> bssid_cam_idx=0
sec_cam_bitmap=00 00 00 00 00 00 00 00
STA [1] 58:00:e3:bb:9c:4f
addr_cam_idx=1
-> bssid_cam_idx=0
sec_cam_bitmap=00 00 00 00 00 00 00 00

addr_cam_idx=2
-> bssid_cam_idx=0
sec_cam_bitmap=00 00 00 00 00 00 00 00
