-Subject: [PATCH] mac80211: fix memory accounting with A-MSDU aggregation
-
-fq uses skb->truesize for memory usage tracking. Increments/decrements
-are done on enqueue/dequeue.
-When A-MSDU aggregation is performed on tx side, the packet is
-aggregated with the last packet in the queue belonging to the same flow.
-There are multiple bugs here:
-- The truesize field of the aggregated packet isn't updated, so memory
-usage is underestimated
-- fq->memory_usage isn't adjusted.
-
-Because of the combination of both bugs, this only causes tx issues in
-rare cases, mainly when the A-MSDU head needs to be reallocated.
-
-Fix this by adjusting both truesize of the A-MSDU head and adding the
-truesize delta to fq->memory_usage.
