Subject: [PATCH] RDMA/nes: report correct port state if interface is down
Date: Mon, 23 Aug 2010 09:32:36 -0500	[thread overview]
Message-ID: <20100823143236.GA6592@CTUNG-MOBL1> (raw)


With commit cd6860eb03 we no longer remove nes interface on
ifdown.  On nes_query_port add additional check to net queue
and report IB_PORT_DOWN if the queue is not running.
