[PATCH] net: macb: Correct the MID field length value

[Michal Simek]

From: Punnaiah Choudary Kalluri <punnaiah.choudary.kalluri@xxxxxxxxxx>

The latest spec "I-IPA01-0266-USR Rev 10" limit the MID field length to 12 bit
value. For previous versions it is 16 bit value.

This change will not break the backward compatibility as the latest ID value is
7 and with in the 12 bit value limit.
