Subject: [PATCH] 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.
