From a0f63ff69f9cb4a9903fac21ea11ba6d2b92c936 Mon Sep 17 00:00:00 2001 From: Ryder Lee Date: Sat, 16 May 2020 03:33:28 +0800 Subject: [PATCH] mt76: mt7915: add spatial reuse support Enable or disable OBSS PD when the bss config changes or we assoc to an AP that broadcasts the IE. With this patch, we can get ~20% gain in OBSS OTA environment.
