libibverbs: Extend support of NDR rates
NDR(106.25 Gbps) support exposed new data rates:
800 Gbps - NDR 8x.
1200 Gbps - NDR 12x.
Utility methods were updated to support the new rates mentioned above:
1) Rate to mult - Convert the IB rate enum to a multiple of 2.5 Gbps.
2) Rate to mbps - Convert IB rate enum to the mbps value.
In addition, speed_str() of ibv_devinfo was updated to consider the new
NDR rate.

kern: wg: remove overly-restrictive address family check
IPv4 packets can be routed via an IPv6 nexthop, so the handling of the
parsed address family is more strict than it needs to be. If we have a
valid header that matches a known peer, then we have no reason to
decline the packet.
Convert it to an assertion that it matches the destination as viewed by
the stack below it, instead. `dst` may be the gateway instead of the
destination in the case of a nexthop, so the `af` assignment must be
switched to use the destination in all cases.
Add a test case that approximates a setup like in the PR and
demonstrates the issue.

vm_object: add getpages utility
vnode_pager_generic_getpages() and swap_pager_getpages_locked() each
include code to read a few pages behind, and a few pages ahead of, a
specified page range. The same code can serve each function, and that
code is encapsulated in a new vm_object_page function. For the swap
case, this also eliminates some needless linked-list traversal.

acpi_pci: Add quirk for DELAY-after-EJ0
On some EC2 instances, there is a race between removing a device from
the system and making the PCI bus stop reporting the presence of the
device. As a result, a PCI BUS_RESCAN performed immediately after
the _EJ0 method returns "sees" the device which is being ejected, which
then causes problems later (e.g. we won't recognize a new device being
plugged into that slot because we never knew it was vacant).
On other operating systems the bus is synchronously marked as needing
to be rescanned but the rescan does not occur until O(1) seconds later.
Create a new ACPI_Q_DELAY_BEFORE_EJECT_RESCAN quirk and set it in EC2
AMIs, and add a 10 ms DELAY between _EJ0 and BUS_RESCAN when tht quirk
is set.

g_dev_orphan(): Return early if the device is already gone
The following panic was the result of running "cdcontrol eject" after
using the physical ejection key on the device before the tray was
actually ejected. So we have hardware racing software.
The device was loaded with a DVD.
Resulted in a NULL pointer dereference
g_dev_orphan() at g_dev_orphan+0x2e/frame 0xfffffe01eba0a9f0
g_resize_provider_event() at g_resize_provider_event+0x71/frame 0xfffffe01eba0aa20

fork_exit() at fork_exit+0x85/frame 0xfffffe01eba0aab0
fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe01eba0aab0
Avoid this possibility and return early of dev is NULL already.

Enable LLVM_BINUTILS by default
Starting in 2014 FreeBSD migrated from GNU binutils to ELF Tool Chain
tools. At that time there were no usable LLVM versions of those tools,
but they have been developing rapidly since then. Migrate to LLVML's
tools for both functionality and maintainability reasons.
This will eventually support the use of link-time optimization (LTO) in
the FreeBSD base system. LTO runs optimization passes over the entire
executable (or library) at link time and thus allows for more effective
optimization than when performed on individual compilation units.
When using LTO object files (.o) including those contained in static
library archives (.a) contain LLVM IR bitcode rather than target
object code. This means that utilities that operate on object files
need to support LLVM IR.
As with ELF Tool Chain the LLVM tools aim for command line and output
format compatibility with GNU binutils, although there are a few minor

LinuxKPI: always use contig allocations in linux_alloc_kmem()
In linux_alloc_kmem() [used by *get_page*()] we always at least allocate
PAGE_SIZE and we want the allocation to be contiguous so it can be passed
to DMA. Always use kmem_alloc_contig() and only change the low argument
depending on the GFP_DMA32 flag being given or not.

In order to guarantee that allocations are contiguous even if using

This makes use of 9e6544dd6e02 (and following) allowing free(9) to
