From 47f754b3f838205f3b25c4839f74801d180995bf Mon Sep 17 00:00:00 2001 From: Bitterblue Smith Date: Tue, 22 Oct 2024 20:20:26 +0300 Subject: [PATCH] wifi: rtw88: Report the signal strength only if it's known RTL8811CU doesn't report the signal strength for many (any?) data frames. When the signal strength is not known, set RX_FLAG_NO_SIGNAL_VAL in order to avoid reporting a signal strength of 0.
