I am not sure about motivation to switch to "Kbytes/sec" -- I've seen a
target that does 700 *bytes* per second, so your code will just print '0'
in that case -- is that intended?

You've changed the code to output the number of bytes and changes the text
to read "bytes" the the name of output field is still 'transferred-bits'.
I'm not sure this matters (maybe in MI mode), but in any way, you should
adjust that.
