This is the first of two pull requests. It is the smaller request, but touches for more different things (this is everything but what is in or going into staging). The pull request for the code in staging/rdma is on hold until after we decide what to do on the write/writev API issue and may be partially deferred until 4.7 as a result. Summary: - cxgb4 updates - nes updates - unification of iwarp portmapper code to core - add drain_cq API - various ib_core updates - minor ipoib updates - minor mlx4 updates - more significant mlx5 updates (including a minor merge conflict with net-next tree...merge is simple to resolve and Stephen's resolution was confirmed by Mellanox) - trivial net/9p rdma conversion - ocrdma RoCEv2 update - srpt updates" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (85 commits) iwpm: crash fix for large connections test iw_cxgb3: support for iWARP port mapping iw_cxgb4: remove port mapper related code iw_nes: remove port mapper related code iwcm: common code for port mapper net/9p: convert to new CQ API IB/mlx5: Add support for don't trap rules net/mlx5_core: Introduce forward to next priority action net/mlx5_core: Create anchor of last flow table iser: Accept arbitrary sg lists mapping if the device supports it mlx5: Add arbitrary sg list support IB/core: Add arbitrary sg_list support IB/mlx5: Expose correct max_fast_reg_page_list_len IB/mlx5: Make coding style more consistent IB/mlx5: Convert UMR CQ to new CQ API IB/ocrdma: Skip using unneeded intermediate variable IB/ocrdma: Skip using unneeded intermediate variable IB/ocrdma: Delete unnecessary variable initialisations in 11 functions IB/core: Documentation fix in the MAD header file IB/core: trivial prink cleanup. ...
