Please apply the following patch series for smc to netdev's net-next tree.

SMC-Dv2 support (see https://www.ibm.com/support/pages/node/6326337)
provides multi-subnet support for SMC-D, eliminating the current
same-subnet restriction. The new version detects if any of the virtual
ISM devices are on the same system and can therefore be used for an
SMC-Dv2 connection. Furthermore, SMC-Dv2 eliminates the need for
PNET IDs on s390.

Karsten Graul (1):
  net/smc: remove constant and introduce helper to check for a pnet id

Ursula Braun (13):
  net/smc: CLC header fields renaming
  net/smc: separate find device functions
  net/smc: split CLC confirm/accept data to be sent
  net/smc: prepare for more proposed ISM devices
  net/smc: introduce System Enterprise ID (SEID)
  net/smc: introduce CHID callback for ISM devices
  net/smc: introduce list of pnetids for Ethernet devices
  net/smc: determine proposed ISM devices
  net/smc: build and send V2 CLC proposal
  net/smc: determine accepted ISM devices
  net/smc: CLC accept / confirm V2
  net/smc: introduce CLC first contact extension
  net/smc: CLC decline - V2 enhancements
