Subject: [PATCH] ath10k: Fix DMA burst size
Date: Mon, 29 Dec 2014 11:51:06 +0530 [thread overview]
Message-ID: <1419834066-11802-1-git-send-email-sujith@msujith.org> (raw)
From: Sujith Manoharan <c_manoha@qca.qualcomm.com>
A value of zero indicates that 128B is the maximum
DMA request size for read/writes. But PCI cards based
on AR9880 can support 256B, so enable this for
the 10.2 firmware.
