[ofa-general] [GIT PULL] OFED 1.2 uDAPL release notes

[Tang, Changqing]

Sean:
	Thanks, I think this solve our problem. Currently two cards are
on different subnet. Code on either subnet is working reliablely. I have
not tried if all cards are on the same subnet.

	Do you recommend to config as a single subnet or two subnets ?
