Subject: [net-next-2.6 PATCH] enic: Bug Fix: Dont reset ENIC_SET_APPLIED flag
	on port profile disassociate

From: Roopa Prabhu <roprabhu@...co.com>

enic_get_vf_port returns port profile operation status only if ENIC_SET_APPLIED
flag is set. A recent rework of enic_set_port_profile added code to reset this
flag on disassociate. As a result of which a client calling enic_get_vf_port
to get the status of port profile disassociate will always get a return value
of ENODATA. This patch renames ENIC_SET_APPLIED to more appropriate
ENIC_PORT_REQUEST_APPLIED and reverts back the recent change so that the
flag is set both at associate and disassociate of a port profile.
