Probably, although if you are not directly connected (direct cross-over
ethernet cable), then your ethernet switch may drop them. Or your receiving
eth hardware on your PC may drop them and not report them up.
As I said, best thing to do is debug your driver to see if it's even
attempting to send stuff, and if so, what.

lwip will do the right thing yes. I can't vouch for any ethernet driver you
have written of course.

If you've already set the BYTE_ORDER, then I think the problem is probably
in your driver.
