+
+For unknown reasons printk() on some context can cause CPU hung on
+embedded MT7620 AP/router MIPS platforms. What can result on wifi
+disconnects.
+
+This patch move queue full messages to debug level what is consistent
+with other mac80211 drivers which drop packet silently if tx queue is
+full. This make MT7620 OpenWRT routers more stable, what was reported
+by various users.
