Subject: [PATCH 1/2] ath10k: fix HTT Tx CE ring size
Date: Tue, 1 Mar 2016 13:16:10 +0100 [thread overview]
Message-ID: <1456834571-9847-1-git-send-email-michal.kazior@tieto.com> (raw)
QCA4019 can queue up to 2500 frames at a time.
This means it requires roughly 5000 entires on the
ring to work properly. Otherwise random tx failure
may occur.
