Have you tested USB gathet Ethernet ?
It works when MUSB_PIO_ONLY is enabled.
When USB_TI_CPPI41_DMA is enabled, it is able receive data, but isn't
able to transfer data.

You put the "ifeq($(CONFIG_USB_TUSB_OMAP_DMA),y)" in the
"ifeq ($(CONFIG_USB_TI_CPPI41_DMA),y) ..... endif".
So if CONFIG_USB_TI_CPPI41_DMA is not enabled, tusb6010_omap.c will
not be compiled.
Hum, you're right. The patch is broken -- there should be 'else'
there...
