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 Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> --- drivers/net/wireless/realtek/rtw89/debug.c | 36 ++++++++++++++++++++++ 1 file changed, 36 insertions(+)
