Please fix the email subject 2. It seems that some places may need checks to exclude mt7921. 3. Some duplication in debugfs.c 4. mt792x_mcu_set_perf_ind could be static 5. Check if the pointer derefs in mt792x_perf_account_rx are safe. Aside from this, I also have some questions: - is this on by default or can it only be enabled via debugfs? - why does the host have to keep statistics on tx/rx, when the firmware could do that and handle it internally? Thanks, - Felix
