Subject: iwlwifi: mvm: don't enable protection for all AMPDUs
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=7f5bd0422e0a85dc48418de3950b7726f3fc5a7d;p=openwrt%2Fstaging%2Fblogic.git

iwlwifi: mvm: don't enable protection for all AMPDUs

Currently RTS protection was done whenever trasnmitting an AMPDU.
This limits throughput in cases where there's no need for protection.
Disable this too inclusive protection for now.
