From 9e32058ae62f1d8fdf1ee7b177a1307f90335fbd Mon Sep 17 00:00:00 2001 From: Karthikeyan Periyasamy Date: Tue, 11 Jun 2024 09:42:33 +0300 Subject: [PATCH] wifi: ath12k: avoid unnecessary MSDU drop in the Rx error process Currently, in the Rx error processing handler, once an MSDU drop is detected, the subsequent MSDUs get unintentionally dropped due to the previous drop flag being retained across all MSDU processing, leading to the discarding of valid MSDUs. To resolve this issue, the drop flag should be reset to false before processing each descriptor.
