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: cfg80211: move A-MSDU check in
|
|
ieee80211_data_to_8023_exthdr
|
|
|
|
When parsing the outer A-MSDU header, don't check for inner bridge tunnel
|
|
or RFC1042 headers. This is handled by ieee80211_amsdu_to_8023s already.
