From 0ffa1ba81b35ba147c9df6206a61499a156b0128 Mon Sep 17 00:00:00 2001 From: Bitterblue Smith Date: Fri, 2 May 2025 14:49:01 +0300 Subject: [PATCH] wifi: rtw88: Fix RX aggregation settings for RTL8723DS Use the same RX aggregation size and timeout used by the out-of-tree RTL8723DS driver. Also set mystery bit 31 of REG_RXDMA_AGG_PG_TH. This improves the RX speed from ~44 Mbps to ~67 Mbps.
