Subject: [PATCH 2/9] ath10k: copy tx fetch indication message
Date: Tue, 22 Mar 2016 17:22:12 +0530	[thread overview]
Message-ID: <1458647539-17213-3-git-send-email-rmanohar@qti.qualcomm.com> (raw)
In-Reply-To: <1458647539-17213-1-git-send-email-rmanohar@qti.qualcomm.com>

To optmize CPU usage htt rx descriptors will be reused instead of
refilling it for htt rx copy engine (CE5). To support that all htt rx
indications should be proecssed at same context. Instead of queueing
actual indication message, queue copied message for txrx processing.
