It is worth to mention that caching ib_name is wrong as IB/core provides
IB device rename functionality.

In our case we hit this code path where we pass *PCI_ID*
as the *ib_name* using *smc_pnet* tool(smc_pnet -a <pnet_name> -D
<PCI_ID>). I believe PCI_ID will not change, so caching it here is fine.
