net: dc2114x: allow users to decide whether to detect the tx No Carrier errors
Some IP cores of dc2114x or its variants do not comply so well with
the behaviors described by the official document. A packet could be
sent successfully but reported with No Carrier error. Latest drivers
of this IP core have not detect this error anymore.
