> SMC_outw invokes an endian-aware I/O accessor, which may change the data
> endianness before writing to the device. This is not suitable for data
> transfers where the memory buffer is simply a string of bytes that does
> not require any byte-swapping.
> 
> This patches fixes the smc91x SMC_PUSH_DATA macro so that it uses the
> string I/O accessor for outputting the leading or trailing halfwords on
> halfword-aligned buffers.
