up to 2 rx/tx queues for the 82574.
Program the 82574 to enable 5 msix vectors, assign 1 to each rx queue,
1 to each tx queue and 1 to the link handler.
Inspired by DragonFlyBSD, enable some RSS logic for handling tx queue
handling/processing.
Move multiqueue handler functions so that they line up better in a diff
review to if_igb.c
Always enqueue tx work to be done in em_mq_start, if unable to acquire
the TX lock, then this will be processed in the background later by the
taskqueue. Remove mbuf argument from em_start_mq_locked() as the work
is always enqueued. (stolen from igb)
Setup TARC, TXDCTL and RXDCTL registers for better performance and stability
in multiqueue and singlequeue implementations. Handle Intel errata 3 and
generic multiqueue behavior with the initialization of TARC(0) and TARC(1)
Bind interrupt threads to cpus in order. (stolen from igb)
Add 2 new DDB functions, one to display the queue(s) and their settings and
one to reset the adapter. Primarily used for debugging.
In the multiqueue configuration, bump RXD and TXD ring size to max for the
adapter (4096). Setup an RDTR of 64 and an RADV of 128 in multiqueue configuration
to cut down on the number of interrupts. RADV was arbitrarily set to 2x RDTR
and can be adjusted as needed.
Cleanup the display in top a bit to make it clearer where the taskqueue threads
are running and what they should be doing.
Ensure that both queues are processed by em_local_timer() by writing them both
to the IMS register to generate soft interrupts.
Ensure that an soft interrupt is generated when em_msix_link() is run so that
any races between assertion of the link/status interrupt and a rx/tx interrupt
are handled.

GICv3 allows to distribute interrupts to more than 8 cores served by
the previous GIC revisions. GICv3 introduces additional logic in form
of Re-Distributors associated with particular CPUs to determine
the highest priority interrupts and manage PPIs and LPIs
(Locality-specific Peripheral Interrupts). Interrupts routing is
based on CPUs' affinity numbers. CPU interface was changed to be
accessible via CPU System Registers and this is the preferred
(and supported) method in this driver.

The x86 busdma subsystem allows using multiple implementations.
By default the classic bounce buffer approach is used, however
on systems with IOMMU it could be in runtime switched to more
efficient hardware accelerated implementation.
This commit adds ARM64 port of the x86 busdma framework and bounce
buffer backend. It is ready to use on IO coherent systems. If the
IO coherency cannot be guaranteed, the cache management operations have
to be added to this code in places marked by /* XXX ARM64TODO (...) */
comments. Also IOMMU support might be added by registering another
busdma implementation like it is already done on the x86.

In order to map memory from other domains when running on Xen FreeBSD uses
unused physical memory regions. Until now this memory has been allocated
using bus_alloc_resource, but this is not completely safe as we can end up
using unreclaimed MMIO or ACPI regions.
Fix this by introducing a new newbus method that can be used by Xen drivers
to request for unused memory regions. On amd64 we make sure this memory
comes from regions above 4GB in order to prevent clashes with MMIO/ACPI
regions. On i386 there's nothing we can do, so just fall back to the
previous mechanism.

The only thing is used from this code is ipip_output() function, that does
IPIP encapsulation. Other parts of XF_IP4 code were removed in r275133.
Also it isn't possible to configure the use of XF_IP4, nor from userland

Simplify the ipip_output() function and rename it to ipsec_encap().
* move IP_DF handling from ipsec4_process_packet() into ipsec_encap();
* since ipsec_encap() called from ipsec[64]_process_packet(), it
is safe to assume that mbuf is contiguous at least to IP header
for used IP version. Remove all unneeded m_pullup(), m_copydata
and related checks.
* use V_ip_defttl and V_ip6_defhlim for outer headers;
* use V_ip4_ipsec_ecn and V_ip6_ipsec_ecn for outer headers;
* move all diagnostic messages to the ipsec_encap() callers;

The option allows to have nx permissions for memory mappings on i386

sizing problems typical for the PAE config.
Intel documented that the PAE format for page tables is available
starting with the Pentium Pro, but it is possible that the plain
