Subject: iwlwifi: mvm: limit aggregation size in low latency to 6
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ddfc1593737f36a04ec5e23e9cb0c6b2bad3f3a6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

iwlwifi: mvm: limit aggregation size in low latency to 6

This is a tradeoff between enabling better throughput for
bursty traffic and low latency. The number 6 was found to be
a good tradeoff for the Miracast use case which is the
major use case for low latency.
