From 43beae558596d733eb96542be43ad04acc373278 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Fri, 19 Jan 2024 11:52:50 +0100 Subject: [PATCH] mac80211: silence warning for missing rate information (#3163) Silence warnings for missing rate information. These warnings do not provide value. Instead, they might rotate more crucial information out of the kernel message ringbuffer.
