A count of frames received on a particular
interface that are an integral number of octets in
length but do not pass the FCS check.
The count represented by an instance of this
object is incremented when the frameCheckError

(or other MAC user). Received frames for which
multiple error conditions obtain are, according to
the conventions of [9], counted exclusively
according to the error status presented to the
LLC.
