# 368220 01-Dec-2020 hselasky

MFC r367716:
Use mlx5core to create/destroy all Dynamically Connected Targets, DCTs.

To prevent a hardware memory leak when a DEVX DCT object is destroyed
without calling drain DCT before, (e.g. under cleanup flow), need to
manage its creation and destruction via mlx5 core.

# 337114 02-Aug-2018 hselasky

MFC r336450:
Do not inline transmit headers and use HW VLAN tagging if supported by mlx5en(4).

Query the minimal inline mode supported by the card.
When creating a send queue, cache the queried mode and optimize the transmit
if no inlining is required. In this case, we can avoid touching the headers
cache line and avoid dirtying several more lines by copying headers into
the send WQEs. Also, if no inline headers are used, hardware assists in
the VLAN tag framing.

r326169, r326563, r326649, r326716, r326764, r326765 and r329222:

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.

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.

ipoib: Bound the number of egress mbufs buffered during pathrec lookups.

In pathological situations where the master subnet manager becomes

This addresses the same issue as commit 1e85b806f9 in Linux.

# 290650 10-Nov-2015 hselasky

Add mlx5 and mlx5en driver(s) for ConnectX-4 and ConnectX-4LX cards
from Mellanox Technologies. The current driver supports ethernet
speeds up to and including 100 GBit/s. Infiniband support will be
done later.

The code added is not compiled by default, which will be done by a
separate commit.
