    Subject[PATCH 5.10 48/54] wifi: mac80211_hwsim: avoid mac80211 warning on bad rate
    Date
    From: Johannes Berg <johannes.berg@intel.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).
