sfc: Use TX PIO for sufficiently small packets
Sufficiently small linear packets can be copied into the PIO buffer
with a single call to memcpy_toio(). Non-linear packets require an
intermediate cache-line-sized buffer.
[bwh: I wrote the first version of this, but Jon did the hard work to
handle non-linear packets.]
