You mean you're just sending packet data from serial? I thought maybe you
were maybe redirecting entire packets including headers from serial. IF
that's not happening, that's okay.

It probably is a problem in your driver in that case.

To debug it, first start comparing what you think you're sending in the
emac driver with what wireshark reports actually got sent to find the
difference.

You can look through your driver for places where some buffer data could be
reused before it was really finished with. That sort of thing might be a cause.
