	Hi,
	 
	The patch disable av port checking (part of check-in 1538).
	The problem of checking av port happen with mthca card (ConnectX
cards are OK).
	OpenSM (runs on one machine) sends MAD request to another at the
beginning.
	During request processing an av is created with mad svc port
num. This field is taken from qp_attr.primary_port
	after query on the qp, but mthca set primary_port attr to be
zero (among other fields in qp_attr).
	That will cause the av creation to fail and in consequence
opensm fails to recognize the remote machine.
	 
	Thanks, Reuven.
