This explains why I don't see them in my mailbox. However, as I can see at http://lists.denx.de/pipermail/u-boot/2014-May/179218.html you are still sandwiching interface, tx_currdescnum and rx_currdescnum between the DMA aligned stuff. This does not really improve packing. -- Best regards, Siarhei Siamashka -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
