Merge branch 'smc-pnetid-and-SMC-D-support'
Ursula Braun says:
====================
smc: pnetid and SMC-D support
SMC requires a configured pnet table to map Ethernet interfaces to
RoCE adapter ports. For s390 there exists hardware support to group
such devices. The first three patches cover the s390 pnetid support,
enabling SMC-R usage on s390 without configuring an extra pnet table.
SMC currently requires RoCE adapters, and uses RDMA-techniques
implemented with IB-verbs. But s390 offers another method for
intra-CEC Shared Memory communication. The following seven patches
implement a solution to run SMC traffic based on intra-CEC DMA,
called SMC-D.
