So instead of virt_to_phys you should use dma_addr??
No, you clearly can't use the bus address. That has no relationship to
the CPU view, even in cases as common as VT-d on x86.
By the way, this usage of virt_to_phys() is not new to the commit that
Dan referenced. It has been there since day one of the iw_cxgb[34]
drivers. This doesn't mean its correct however. :)
