wifi: rtw89: add use of pkt_list offload to debug entry
|
|
|
|
Driver can prepare pkt_list for firmware that only uses them to send out
|
|
the packets in specific situations. To understand the usage of current
|
|
status, and to check if there is leakage problem, dump bitmap and the
|
|
indices used by certain function.
|
|
|
|
An example looks like:
|
|
|
|
map:
|
|
...
|
|
pkt_ofld: 3f 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ...
|
|
[SCAN 0]: 3
|
|
[SCAN 1]: 4
|
|
[SCAN 3]: 5
|
|
VIF [0] xx:xx:xx:xx:xx:xx
|
|
...
|
|
pkt_ofld[GENERAL]: 0 1 2
