Subject: [PATCH net-next v2 00/11] net/smc: introduce SMC-Rv2 support

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

SMC-Rv2 support (see https://www.ibm.com/support/pages/node/6326337)
provides routable RoCE support for SMC-R, eliminating the current
same-subnet restriction, by exploiting the UDP encapsulation feature
of the RoCE adapter hardware.

Patch 1 ("net/smc: improved fix wait on already cleared link") is
already applied on netdevs net tree but its changes are needed for
this series on net-next. The patch is unchanged compared to the
version on the net tree.

v2: resend of the v1 patch series, and CC linux-rdma this time

Karsten Graul (11):
  net/smc: improved fix wait on already cleared link
  net/smc: save stack space and allocate smc_init_info
  net/smc: prepare for SMC-Rv2 connection
  net/smc: add SMC-Rv2 connection establishment
  net/smc: add listen processing for SMC-Rv2
  net/smc: add v2 format of CLC decline message
  net/smc: retrieve v2 gid from IB device
  net/smc: add v2 support to the work request layer
  net/smc: extend LLC layer for SMC-Rv2
  net/smc: add netlink support for SMC-Rv2
  net/smc: stop links when their GID is removed
