The standard defines the A-MSDU header length field differently for mesh compared to other modes. Deal with this accordingly and work around broken implementations (e.g. ath10k, ath11k). Signed-off-by: Felix Fietkau <nbd@nbd.name>

Subject: [PATCH] wifi: mac80211: remove mesh forwarding congestion check
|
|
|
|
Now that all drivers use iTXQ, it does not make sense to check to drop
|
|
tx forwarding packets when the driver has stopped the queues.
|
|
fq_codel will take care of dropping packets when the queues fill up
|
