mt76: do not attempt to reorder received 802.3 packets without agg session

2022-05-13T07:39:35Z

Fixes potential latency / packet drop issues in cases where a BA session has not (yet) been established. Fixes: e195dad14115 ("mt76: add support for 802.3 rx frames") Signed-off-by: Felix Fietkau

mt76: fix rx reordering with non explicit / psmp ack policy

2022-05-13T07:39:34Z

When the QoS ack policy was set to non explicit / psmp ack, frames are treated as not being part of a BA session, which causes extra latency on reordering. Fix this by only bypassing reordering for packets with no-ack policy Signed-off-by: Felix Fietkau

mt76: report Rx timestamp

2021-04-12T21:07:24Z

Frame reception timestamp (low 32-bits) that indicates the value of the local TSF timer value at the time the first bit of the MAC header in the received frame (PPDU unit) arriving at the MAC. Signed-off-by: Ryder Lee Signed-off-by: Felix Fietkau

mt76: clear skb pointers from rx aggregation reorder buffer during cleanup

2020-02-14T09:06:02Z

During the cleanup of the aggregation session, a rx handler (or release timer) on another CPU might still hold a pointer to the reorder buffer and could attempt to release some packets. Clearing pointers during cleanup avoids a theoretical use-after-free bug here. Signed-off-by: Felix Fietkau

mt76: use AC specific reorder timeout

2020-02-14T09:06:01Z

Before this patch, mt76 handled rx traffic for all TIDs equally, when released from reorder buffer early. This patch uses an AC specific reorder timeout, in order to release partial aggregated frames for video ACs earlier. Voice ACs are currently not aggregated (thanks to Felix for this hint). For example, ath10k also uses AC specific reorder timeouts (reported by firmware in that case). Signed-off-by: Markus Theil Signed-off-by: Felix Fietkau

wireless/mediatek: Replace rcu_swap_protected() with rcu_replace_pointer()

2019-12-12T18:20:51Z

This commit replaces the use of rcu_swap_protected() with the more intuitively appealing rcu_replace_pointer() as a step towards removing rcu_swap_protected().

mt76: fix aggregation stop issue

Cancel the workqueue after the tid has been cleaned up, in order to avoid a possible rescheduling from within the work function. Signed-off-by: Felix Fietkau
