Subject: [PATCH 1/4] Revert "mt76: use IEEE80211_OFFLOAD_ENCAP_ENABLED instead of MT_DRV_AMSDU_OFFLOAD"
Date: Mon,  3 Oct 2022 11:32:03 +0200	[thread overview]
Message-ID: <20221003093206.86323-1-nbd@nbd.name> (raw)

From: Ben Greear <greearb@candelatech.com>

This reverts commit f17f4864504d754bcbf31e4c89412cdf9946c409 and adds the
MT_DRV_AMSDU_OFFLOAD flag for MT7921 USB/SDIO

The reverted commit significantly decreases performance when running
a test where two MT7915 radios have 16 station vdevs each, configured
for AC mode, and transmitting UDP traffic to AP.
