RoCE/infiniband/iWarp upgrade to Linux 4.9 for kernel and userspace. This commit merges projects/bsd_rdma_4_9 to 11-stable.
Compatibility wrappers have been made for existing 11-stable ibcore APIs, including ib_reg_phys_mr(). Refer to "sys/ofed/include/rdma/ib_verbs_compat.h" for more information.
The iw_cxgb driver has not been updated and has been disconnected from the build.

NOTES: ======
1) The mthca driver has been removed from userspace. 2) All GPLv2 only sources have been removed and where applicable rewritten from scratch under a BSD license. 3) List of fully supported drivers in userspace and kernel: a) iw_cxgbe (Chelsio) b) mlx4ib (Mellanox) c) mlx5ib (Mellanox) 4) WITH_OFED=YES is still required by make in order to build OFED userspace and kernel code. 5) Full support has been added for routable RoCE, RoCE v2.
MFC r326649: Disconnect OFED after r326169 broke all DIRDEPS support for it.
MFC r326716: Correctly define the unordered_map namespace in ofed/libibnetdisc .
This should fix ofed/libibnetdisc compilation with C-compilers different from clang and GCC v4.2.1.

MFC r326764: ofed: Remove duplicated symbols from the version file.
ld.bfd accepts multiple listing of the same symbol in the version script. lld is stricter and errors out. Since arm64 and sometimes amd64 use lld, we should correct this cosmetic issue.

MFC r326765: ofed: Define barriers for mips and arm.
I used the strongest barriers available on the architectures, so if the future analysis show that it is excessive, the barriers could be relaxed. Still, it is unlikely that it is meaningful to run IB on 32bit ARM or current MIPS machines, so the change is to make WITH_OFED to pass tinderbox.

This is simpler than the hand-rolled queue, and fixes a use-after-free.

MFC r303512: sdp: Use malloc(9) instead of the Linux compat layer.
SDP transmit and receive rings are always created in a sleepable context, so we can use M_WAITOK and remove error checks.

MFC r303513: sdp: Destroy the RDMA ID after destroying the connection's queue pair.
This is the ordering documented by rdma_destroy_qp(). Also add a useful KASSERT to sdp_pcbfree().

MFC r303646: ipoib: Bound the number of egress mbufs buffered during pathrec lookups.
In pathological situations where the master subnet manager becomes unresponsive for an extended period, we may otherwise end up queuing all of the system's mbufs while waiting for a response to a path record lookup.
This addresses the same issue as commit 1e85b806f9 in Linux.

MFC r329222: Import the mthca kernel side infiniband driver from Linux 4.9 and fix compilation under FreeBSD. The mthca driver was temporarily removed as part of the Linux 4.9 RoCE/infinband upgrade.

MFC r306486-r325841: Update the mlx4, mlx4ib(4) and mlx4en(4) drivers to match FreeBSD-head prior to the Linux 4.9 RoCE/infiniband upgrade.
Sponsored by: Mellanox Technologies
MFC r306486: Move the ConnectX-3 and ConnectX-2 driver from sys/ofed into sys/dev/mlx4 like other PCI network drivers. The sys/ofed directory is now mainly reserved for generic infiniband code, with exception of the mthca driver.
- Add new manual page, mlx4en(4), describing how to configure and load mlx4en.
- All relevant driver C-files are now prefixed mlx4, mlx4_en and mlx4_ib respectivly to avoid object filename collisions when compiling the kernel. This also fixes an issue with proper dependency file generation for the C-files in question.
- Device mlxen is now device mlx4en and depends on device mlx4, see mlx4en(4). Only the network device name remains unchanged.
- The mlx4 and mlx4en modules are now built by default on i386 and amd64 targets. Only building the mlx4ib module depends on WITH_OFED=YES .

MFC r325841: Update the mlx4 core and mlx4en(4) modules towards Linux v4.9.
Background: The coming ibcore update forces an update of mlx4ib(4) which in turn requires an updated mlx4 core module. This also affects the mlx4en(4) module because commonly used APIs are updated. This commit is a middle step updating the mlx4 modules towards the new ibcore.
This change contains no major new features.
Changes in mlx4: a) Improved error handling when mlx4 PCI devices are detached inside VMs. b) Major update of codebase towards Linux 4.9.
Changes in mlx4ib(4): a) Minimal changes needed in order to compile using the updated mlx4 core APIs.
Changes in mlx4en(4): a) Update flow steering code in mlx4en to use new APIs for registering MAC addresses and IP addresses. b) Update all statistics counters to be 64-bit. c) Minimal changes needed in order to compile using the updated mlx4 core APIs.
