Thanks a lot!

I have just browsed the driver and I noticed that there is room for performance
improvements in netvia_tsa.c w.r.t memcpy(). You can avoid the memcpy() call
for received packets by using invalidate_dcache_range(). I did this for
the 8xx_io/enet.c driver a few weeks ago(it's not in BK yet).
