From b649678c18cac4b7c85d7d7d86d17e9e4c9b7641 Mon Sep 17 00:00:00 2001 From: Shayne Chen Date: Mon, 18 Oct 2021 16:09:41 +0800 Subject: [PATCH] mt76: mt7915: change max rx len limit of hw modules Update max rx len of some hw modules, which aligns out vendor SDK. In normal modes, we exchange MPDU 7991 cap with peers; however, this won't play a part in sniffer mode. To prevent packets which exceed the max MPDU size from entering specific rx path in hw, we need to set a proper limit to filter them out.
