Until now, DPAA2 driver was configured to drop any packet which
was marked as malformed by hardware - which included those with
wrong checksum.
With this patch, that configuration has been removed - hereafter,
all packets arriving on a DPMAC link would be forwarded to a DPNI
and further processing would be done as configured for a standard
packet path.
