From 1bb9a8a4c81d0305c511a0919cd30ebfa91915ae Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 28 May 2020 21:34:38 +0200 Subject: mac80211: use HE 6 GHz band capability and pass it to the driver In order to handle 6 GHz AP side, take the HE 6 GHz band capability data and pass it to the driver (which needs it for A-MPDU spacing and A-MPDU length).
