robert-hh ea09dccfea mimxrt: Re-Enable eth checksum creation by HW.
The initial problem with a wrong ICMP checksum was caused by
the test code setting a checksum and the HW taking that probably as
the start value and ending up with 0xffff. With a checksum field of 0
set by the test code the HW creates the proper checksum.
