Subject: [PATCH net-next 6/6] net/smc: allow PCI IDs as ib device names in the pnet table

From: Hans Wippel <hwippel@...ux.ibm.com>

SMC-D devices are identified by their PCI IDs in the pnet table. In
order to make usage of the pnet table more consistent for users, this
patch adds this form of identification for ib devices as well.
