Changed E100 device so it updates EOF, F, and Actual Count fields of Receive
Frame Descriptor (RFD).
Actual Count fields were updated before this patch I think?
Assuming RFD.actual_count equals to size.

Then this line can be removed, or what's maybe even better, you can just
reuse rfd_size.

We need a better title, e.g "Fixing EOF and F filed when updating RFD"
Thanks
