Subject: [PATCH 5.4 35/38] wifi: mac80211_hwsim: avoid mac80211 warning on bad rate
From: Johannes Berg <johannes.berg@...el.com>
commit 1833b6f46d7e2830251a063935ab464256defe22 upstream.
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).
