From 7b4c876961ad6ddcfacd69b25fe7e13ff41fe322 Mon Sep 17 00:00:00 2001 From: Eli Cohen Date: Mon, 27 Sep 2010 17:51:11 -0700 Subject: IPoIB: Skip IBoE ports IPoIB is IP-over-Infiniband link layer. In the case of IBoE, the link layer is Ethernet and IP can work directly over Ethernet, so disable IPoIB for non-IB_LINK_LAYER_INFINIBAND ports.

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