Subject: mac80211: fix per-TID RX-MSDU counter
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3d6dc3431e944cf800637404167447f4badffdba;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mac80211: fix per-TID RX-MSDU counter

In the case of non-QoS association, the counter was actually
wrong. The right index isn't security_idx but seqno_idx, as
security_idx will be 0 for data frames, while 16 is needed.
