Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull Mellanox rdma updates from Doug Ledford:
 "Mellanox specific updates for 4.11 merge window

  Because the Mellanox code required being based on a net-next tree, I
  keept it separate from the remainder of the RDMA stack submission that
  is based on 4.10-rc3.

  This branch contains:

   - Various mlx4 and mlx5 fixes and minor changes

   - Support for adding a tag match rule to flow specs

   - Support for cvlan offload operation for raw ethernet QPs

   - A change to the core IB code to recognize raw eth capabilities and
     enumerate them (touches non-Mellanox code)

   - Implicit On-Demand Paging memory registration support"
