nids(4) was a clever idea in the early 2000's when the market was
flooded with 10/100 NICs with Windows-only drivers, but that hasn't been
the case for ages and the driver has had no meaningful maintenance in
ages. It only supports Windows-XP era drivers.

This restores behavior from before domain iterators were added in
r327895 and r327896.
The vm_domainset_iter_policy() will do a vm_wait_doms() and then
restart its iterator when M_WAITOK is set. It will also force
the containing loop to have M_NOWAIT. So we get an unbounded
retry loop rather than the intended bounded retries that
kmem_alloc_contig_pages() already handles.
This also restores M_WAITOK to the vmem_alloc() call in
kmem_alloc_attr_domain() and kmem_alloc_contig_domain().

Detection of interface type by filter must happen before detection of
interface type by prefix. Else the following sequence of commands will
try to create a LAGG interface instead of a VLAN interface, which
accidentially worked previously, because the date pointed to by the
ifr_data pointer was not parsed by VLAN create ioctl(2). This is a
regression after r368229, because the VLAN creation now parses the
ifr_data field.

PCI memory address space is shared between memory-mapped devices (MMIO)
and host memory (which may be remapped by an IOMMU). Device accesses to
an address within a memory aperture in a PCIe root port will be treated
as peer-to-peer and not forwarded to an IOMMU. To avoid this, reserve
the address space of the root port's memory apertures in the address
space used by the IOMMU for remapping.

To export information from fd tables we have several loops which do
this:
FILDESC_SLOCK(fdp);
for (i = 0; fdp->fd_refcount > 0 && i <= lastfile; i++)
<export info for fd i>;
FILDESC_SUNLOCK(fdp);
Before r367777, fdescfree() acquired the fd table exclusive lock between
decrementing fdp->fd_refcount and freeing table entries. This
serialized with the loop above, so the file at descriptor i would remain
valid until the lock is dropped. Now there is no serialization, so the
loops may race with teardown of file descriptor tables.
Acquire the exclusive fdtable lock after releasing the final table
reference to provide a barrier synchronizing with these loops.
