I am having ethernet performance issue on panda rev A3. TX gets stuck while RX seems fine. At least pinging is ok...
I started a thread on various mailing-list (http://comments.gmane.org/gmane.linux.network/234335).
I made a lot of trials but no luck so far...
My problem may be related to the one described here for usb storage. My kernel already embeds Ming Lei's patch (https://patchwork.kernel.org/patch/1113332/), and CONFIG_ARM_DMA_MEM_BUFFERABLE and CONFIG_ARCH_HAS_BARRIERS are enabled. But still ethernet performance is really poor.
Smsc9514 device driver relies on usbnet. I lack usb knowledge, thus I cannot state whether Ming Lei's patch in ehci-q.c "should" fix my issue if they were related. Otherwise, did anyone find out that CONFIG_PL310_ERRATA_769419 patch above effectively fixes the usb storage issue?
