Avoids false positive on detecting frags or encrypted mgmt frames Signed-off-by: -
Xing Song authored
When received frame is decryped by hardware, CCMP PN is checked by mt76. When management frame protection (IEEE 802.11w) is used, we must use a separate counter for tracking received CCMP packet number for the management frames. The previously used counter was shared with data frames and that can cause problems in detecting replays incorrectly for robust management frames. Add a new counter just for robust management frames to avoid this issue. Signed-off-by:

This adds the new mib counters from last patch into ethtool stats. Signed-off-by:
-
Ben Greear authored
Add register definitions and read & accumulate them in the mib polling logic. Note that some registers should not be read since firmware is already reading them. If driver reads those, they will be cleared-on-read, and so the firmware stats will be incorrect. For these 'do-not-read' stats, add them to the registers definition so that other developers can be aware of these constraints, but do not actually read them in the driver. Signed-off-by:

Ben Greear authored
These counters are clear-on-read, so we need to accumulate them in the update_stats poll logic, and read the accumulated values instead of directly doing register reads when reporting to debugfs and ethtool stats. Signed-off-by:
