Subject: [PATCH 3/3] ath: Enhance radar detection by looking up chirp
Date: Thu, 12 Feb 2015 13:17:05 -0800	[thread overview]
Message-ID: <1423775825-19498-3-git-send-email-poh@qca.qualcomm.com> (raw)
In-Reply-To: <1423775825-19498-1-git-send-email-poh@qca.qualcomm.com>

Certain radar types such as FCC radar type 5 are using chirp
in their pulses, hence looking up the chirp status will enhance
to avoid false radar detection.
