Masashi Honma cd486e627e ath9k_htc: Discard undersized packets ... Sometimes the hardware will push small packets that trigger a WARN_ON in mac80211. Discard them early to avoid this issue. This patch ports 2 patches from ath9k to ath9k_htc. commit 3c0efb745a "ath9k: discard undersized packets". commit df5c415050 "ath9k: correctly handle short radar pulses".
