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"
