From 5595870f77c7f9de3481b0c0d5ad03176586556e Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 16 Sep 2020 18:46:11 +0200 Subject: mac80211: allow bigger A-MSDU sizes in VHT, even if HT is limited Some APs (e.g. Asus RT-AC88U) have been observed to report an HT MSDU size limit of 3839 and a VHT limit of 7991. These APs can handle bigger frames than 3839 bytes just fine, so we should remove the VHT limit based on the HT capabilities. This improves tx throughput.
