Subject: [PATCH 1/3] net: macb: turn off endian_swp_pkt_en
Date: Wed, 3 Apr 2013 09:55:43 +0200 [thread overview]
Message-ID: <1364975745-1479-2-git-send-email-s.trumtrar@pengutronix.de> (raw)
In-Reply-To: <1364975745-1479-1-git-send-email-s.trumtrar@pengutronix.de>
The core has a bit for swapping packet data endianism.
Reset default from Cadence is off. Xilinx however, that uses this core on the
Zynq SoCs, opted for on. Turn it off for all devices.
