Mellanox Linux Drivers and Install Script for Mellanox ConnectX-3, ConnectX-3 Pro, ConnectX-4 Lx, ConnectX-4, ConnectX-5 Ex Ethernet adapters.

Fixes:
- Fixed an issue of when the number of channels configured was less than the number of CPUs available, part of the CPUs would not be used by Tx queues.
- Fixed an issue of when the same CQ is connected to some QPs with SRQ and some without, wrong wr_id might be reported by ibv_poll_cq.
- Fixed the issue where establishing TCP connection took too long due to failure of SA PathRecord query callback handler.
- Fixed the issue where lack of high order allocations caused driver load failure. All high order allocations are now changed to order-0 allocations.
- Fixed a backport issue on some OSs, such as RHEL v7.x, where mlx5 driver would support ip link set DEVICE vf NUM rate TXRATE old command, instead of ip link set DEVICE vf NUM max_tx_rate TXRATE min_tx_rate TXRATE new command.
- Fixed the issue of when performing configuration changes, mlx5e counters values were reset.
- Fixed the issue of when using ibv_exp_cqe_ts_to_ns verb to convert a packet's hardware timestamp to UTC time in nanoseconds, the result may appear backwards compared to the converted time of a previous packet.
- Fixed the issue where attempting to establish a RoCE connection on the default GID or on IPv6 link-local address might have failed when two or more netdevices that belong to HCA ports were slaves under a bonding master. This might also have resulted in the following error message in the kernel log: '__ib_-cache_gid_add: unable to add gid fe80:0000:0000:0000:f652:14ff:fe46:7391 error=-28'.


Enhancements:
- Increased the amount of maximum virtual functions (VF) that can be allocated to a physical function (PF) to 127 VF.
- UDP source port for RoCE v2 packets is now calculated by the driver rather than the firmware, achieving better distribution and less congestion. This mechanism works for RDMACM QPs only, and ensures that RDMA connection messages and data messages have the same UDP source port value.
- Added the ability to manually disable Local Loopback regardless of the number of open user-space transport domains.
- Integrated NEO-Host for orchestration and management of host networking into MLNX_OFED package.
