Until support is added to the offload drivers, they need to be able to
reject routes with an IPv6 gateway. To that end add a flag to fib_info
that indicates if any fib_nh has a v6 gateway. The flag allows the drivers
to efficiently know the use of a v6 gateway without walking all fib_nh
tied to a fib_info each time a route is added.
Update mlxsw and rocker to reject the routes with extack message as to why.

family than the outer fib{6}_nh. To that end, replace nhc_has_gw with

Now nhc_family is used to know if the nh_common is part of a fib_nh

In contrast to switching rx irq coalescing off what fixed an issue,
switching tx irq coalescing off is merely a latency optimization,
therefore net-next. As part of this change:
- Remove INTT_0 .. INTT_3 constants, they aren't used.
- Remove comment in rtl_hw_start_8169(), we now have a detailed
description by the code in rtl_set_coalesce().
- Due to switching irq coalescing off per default we don't need the
initialization in rtl_hw_start_8168(). If ethtool is used to switch
on coalescing then rtl_set_coalesce() will configure this register.
For the sake of completeness: This patch just changes the default.
Users still have the option to configure irq coalescing via ethtool.

* Now the encapsulation is not supported for mlx5 VFs. When we try to

This patch changes the returned value and ignore to confuse user.

* When max modify header action is zero, we return -EOPNOTSUPP
directly. In this way, we can ignore wrong message info (e.g.

This merge commit includes some misc shared code updates from mlx5-next branch needed
for net-next.
1) From Maxim, Remove un-used macros and spinlock from mlx5 code.
2) From Aya, Expose Management PCIE info register layout and add rate limit
print macros.
3) From Tariq, Compilation warning fix in fs_core.c
4) From Vu, Huy and Saeed, Improve mlx5 initialization flow:
The goal is to provide a better logical separation of mlx5 core
device initialization flow and will help to seamlessly support
creating different mlx5 device types such as PF, VF and SF
mlx5 sub-function virtual devices.
Mlx5_core driver needs to separate HCA resources from pci resources.
Its initialize/load/unload will be broken into stages:
1. Initialize common data structures
2. Setup function which initializes pci resources (for PF/VF)
or some other specific resources for virtual device
3. Initialize software objects according to hardware capabilities
4. Load all mlx5_core components
It is also necessary to detach mlx5_core mdev name/message from pci
device mdev->pdev name/message for a clearer report/debug of
different mlx5 device types.
