From: Michael Chan <michael.chan@broadcom.com>

Add the HWRM_VNIC_UPDATE message structures and the function to
send the message to firmware.  This message can be used when
disabling and enabling a receive ring within a VNIC.  The mru
which is the maximum receive size of packets received by the
VNIC can be updated.
