Subject: [PATCHv3 6/9] net: fec: use swab32s() instead of cpu_to_be32()
when swap_buffer() is being called, we know for sure, that we need to
byte swap the data. Also this function is called for swapping data in
both directions. Thus cpu_to_be32() is semantically not correct for
all use cases. Use swab32s() to reflect this.
