tg3: copy only needed fields from userspace-provided EEE data

Browse source

The current code overwrites fields in tp->eee with unchecked data from
edata, e.g. the bitmap with supported modes. ethtool properly returns
the received data from get_eee() call, but we have no guarantee that
other users of the ioctl set_eee() interface behave properly too.
Therefore copy only fields which are actually needed.
