Subject: [PATCH] IPoIB: set dev_id field of IPoIB net_device
Date: Mon, 20 Sep 2010 09:05:06 +0200	[thread overview]
Message-ID: <20100920070506.GA12453@mtldesk30> (raw)

Use the net device's dev_id field to encode the port number of the pci device.
This can be used to to associate a net device with the pci device's port. The
encoding is: dev_id = port - 1.
