Subject: [PATCH] rtw88: no need to send additional information to legacy firmware
Git-commit: e5f57ad06adec1dcbfe69f45792a8b9dd4798664
Patch-mainline: v5.8-rc1
References: jsc#SLE-13430, bsc#1176741
The firmware of 11AC devices need more information to support more offload
functions, such as IQK. And 11N devices such as 8723D does not support
offload these function in firmware, there is no need to send these additional
information to firmware when it comes to 11N devices.
