Subject: [PATCH v2 2/4] ath10k: implement wmi_pdev_bss_chan_info_request
Date: Wed, 27 Apr 2016 16:23:20 +0530	[thread overview]
Message-ID: <1461754402-7679-2-git-send-email-rmanohar@qti.qualcomm.com> (raw)
In-Reply-To: <1461754402-7679-1-git-send-email-rmanohar@qti.qualcomm.com>

Add WMI ops to send pdev_bss_chan_info_request command to target.
This command will be used to retrieve updated cycle counters and noise
floor value of current operating channel (bss channel).
