Subject: [PATCH net-next v6 1/2] dts: Add a binding for Synopsys emac max-frame-size
Date: Mon, 20 Jan 2014 05:39:00 -0600 [thread overview]
Message-ID: <1390217941-22967-2-git-send-email-vbridgers2013@gmail.com> (raw)
In-Reply-To: <1390217941-22967-1-git-send-email-vbridgers2013@gmail.com>
This change adds a parameter for the Synopsys 10/100/1000
stmmac Ethernet driver to configure the maximum frame
size supported by the EMAC driver. Synopsys allows the FIFO
sizes to be configured when the cores are built for a particular
device, but do not provide a way for the driver to read
information from the device about the maximum MTU size
supported as limited by the device's FIFO size.

V6: respin for updated net-next
V5: simplify comment on use of max-frame-size
V4: add comments to explain use of max-frame-size with respect
to inconsistent definition and use in the ePAPR v1.1 spec
V3: change snps,max-frame-size to max-frame-size
V2: change snps,max-mtu to snps,max-frame-size
