Hi,
Hm, so the AR9003 series NICs set PHY error _and_ decrypt/CRC error? On radar frames?
Interesting! Have you checked to see if the AR9280 does the same?

Subject: [PATCH] ath9k: decouple RX error checking for DFS
Previous RX error checking was done exclusive-or for different error
types and caused DFS pulse events to be dropped when other error
flags (e.g. CRC) were set simultaneously.
This patch decouples PHY error processing from other types and ensures
that all pulses detected by HW are accounted by the pattern detector.
