Subject: [PATCH v4 4/6] cfg80211: save power spectral density(psd) of regulatory rule
Date: Fri, 24 Sep 2021 06:00:50 -0400 [thread overview]
Message-ID: <20210924100052.32029-5-wgong@codeaurora.org> (raw)
In-Reply-To: <20210924100052.32029-1-wgong@codeaurora.org>
The power spectral density(psd) of regulatory rule should be take
effect to the channels. This patch is to save the values to the
channel which has psd value.
