Subject: mac80211: A-MPDU Tx change tx_status to support Block Ack data
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=483fdcecc564ae6b011148a758517cf561f65678;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mac80211: A-MPDU Tx change tx_status to support Block Ack data

This patch adds fields to ieee80211_tx_status in order to allow block ack
information exchange between low-level driver,mac80211 and rate scaling
module.
