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 include/uapi/linux/smc.h | 17 +- net/smc/af_smc.c | 431 +++++++++++++++++------- net/smc/smc.h | 20 +- net/smc/smc_cdc.c | 7 +- net/smc/smc_clc.c | 147 +++++++-- net/smc/smc_clc.h | 55 +++- net/smc/smc_core.c | 193 +++++++---- net/smc/smc_core.h | 50 ++- net/smc/smc_ib.c | 160 ++++++++- net/smc/smc_ib.h | 16 +- net/smc/smc_llc.c | 684 ++++++++++++++++++++++++++++++--------- net/smc/smc_llc.h | 12 +- net/smc/smc_pnet.c | 41 ++- net/smc/smc_tx.c | 22 +- net/smc/smc_wr.c | 237 ++++++++++++-- net/smc/smc_wr.h | 22 ++ 16 files changed, 1691 insertions(+), 423 deletions(-)
