Log Message:
sun4v: vdsk - restart the ldc state machine when the ldc endpoint resets the
link or a DATA/NACK/DRING_DATA message is received. These changes make the
driver more robust. In a ldom with Solaris 11.4 SRU30 as primary domain (T5
host system) frequent resets and NACK messages are observed.
