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.

===============================
1) rdma-core was cloned from https://github.com/linux-rdma/rdma-core.git
Top commit d65138ef93af30b3ea249f3a84aa6a24ba7f8a75
2) OpenSM was cloned from git://git.openfabrics.org/~halr/opensm.git

4) infiniband-diags was cloned from git://git.openfabrics.org/~iraweiny/infiniband-diags.git
Tag 1.6.7 with some additional patches from Mellanox.
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.

MFC r303505:
sdp: Use an mbufq for received control packets.
This is simpler than the hand-rolled queue, and fixes a use-after-free.

MFC r303506:
sdp: Destroy the PCB lock before freeing to the zone.

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 r320418. Note that the socket lock _is_ the same as so_rcv's lock
in 11 and this is a no-op in this branch.

cxgbe/iw_cxgbe: Set TCP_NODELAY before initiating connection so that
t4_tom picks it up right away. This is less work than waiting for
the connection to be established before applying the setting.

Add new mlx5ib(4) driver to the kernel source tree which supports
Remote DMA over Converged Ethernet, RoCE, for the ConnectX-4 series of
PCI express network cards.
There is currently no user-space support and this driver only supports
kernel side non-routable RoCE V1. The krping kernel module can be used
to test this driver. Full user-space support including RoCE V2 will be
added as part of the ongoing upgrade to ibcore from Linux 4.9. Otherwise
this driver is feature equivalent to mlx4ib(4). The mlx5ib(4) kernel
module will only be built when WITH_OFED=YES is specified.
MFC after: 2 weeks
