From 1833b6f46d7e2830251a063935ab464256defe22 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 5 Oct 2022 15:10:09 +0200 Subject: wifi: mac80211_hwsim: avoid mac80211 warning on bad rate MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If the tool on the other side (e.g. wmediumd) gets confused about the rate, we hit a warning in mac80211. Silence that by effectively duplicating the check here and dropping the frame silently (in mac80211 it's dropped with the warning).
