935c21a18e Set the correct values in the arm aux control register, based on chip type.
The bits in the aux control register vary based on the processor type.  In
the past we've always just set the 'smp' and "broadcast tlb/cache ops' bits,
which worked fine for the first few SoCs we supported.  Now that we support
most of the cortex-a series processors, it's important to get the right bits
set based on the processor type.

d0f3a8b902 xen-netfront: purge page flipping support
Currently neither Linux nor FreeBSD netback supports page flipping. NetBSD
still supports that. It is not sure how many people actually use page
flipping, but page flipping is supposed to be slower than copying nowadays.
It will also shatter frontend / backend address space.

Overall this feature is more of a burden than a benefit.

02b3773ac4 otus(4) - use the local node alloc function so there's space for statistics.
* Use the correct malloc type for node allocation - M_80211_NODE - so
  the default node free method in net80211 will work correctly.
* Fix otus_node_alloc() to suit FreeBSD's net80211.
* .. and actually call otus_node_alloc() so there's space for the
  per-node tx statistics.  Otherwise, well, it will be scribbling over
  random memory.

Tested:

* AR9170, STA mode

fd7b55de48 otus(4) - add initial monitor mode; use lowest rate for EAPOL
The monitor mode stuff is from the openbsd driver, but it doesn't
100% work.  It doesn't seem to get all frames for all BSSes.
However, it's enough to at start debugging things.  That 0xffffffff
write is /I think/ the RX filter, but I am still not 100% sure about
it all.

Then, whilst here, use the lowest rate for EAPOL frames.  This is just
generally a good thing to do.

26b9f0eb98 Only decode fdt data which belongs to the GIC controller.
The interrupts-extended property is a list of controller-specific
interrupt tuples for more than one controller.  The decode routine of
every PIC gets called in the pre-INTRNG code (nexus doesn't know which
device instance belongs to which fdt node), so the GIC code has to
check each FDT node it is asked to decode to ensure it is the owner.

Because in the pre-INTRNG world there can only be one instance of a GIC,
it's safe to cache the results of a positive lookup in a static variable
to avoid the expensive lookups on subsequent calls.

95a3f7fb33 if_ntb: MFV e26a5843: Move MW/DB management to if_ntb
This is the last e26a5843 patch.  The general thrust of the rewrite was
to move more responsibility for Memory Window and Doorbell interrupt
management from the ntb_hw driver to if_ntb.

A number of APIs have been added, removed, or replaced.  The old
DB callback mechanism has been excised.  Instead, callers (if_ntb) are
responsible for configuring MWs and handling their interrupts more
directly.

This adds a tunable, hw.ntb.max_mw_size, allowing users to limit the
size of memory windows used by if_ntb (identical to the Linux modparam
of the same name).

Despite attempts to keep mechanical name changes to separate commits,
some have snuck in here.  At least the driver should be much more
similar to the latest Linux one now -- making porting fixes easier.

aa71f18e47 NTB: Flesh out the rest of the xeon_setup_b2b_mw changes
Move all Xeon secondary register setup to the setup_b2b_mw routine.  We
use subroutines to make it a bit less wordy than the Linux version.

Adds a new tunable, 'hw.ntb.b2b_mw_share'.  By default, it is off
(zero).  If both sides enable it (any non-zero value), the NTB driver
attempts to use only half of a memory window for remote register MMIO
access.

This is still part of the large Linux rewrite (e26a5843).

fe1a66fccf NTB: "Split ntb_hw_intel and ntb_transport drivers"
This Linux commit was more or less a rewrite.  Unfortunately, the commit
log does not give a lot of context for the rewrite.  I have tried to
faithfully follow the changes made upstream, including matching function
names where possible, while churning the FreeBSD driver as little as
possible.

This is the bulk of the rewrite.  There are two groups of changes to
follow in separate commits: fleshing out the rest of the changes to
xeon_setup_b2b_mw(), and some changes to if_ntb.

Yes, this is a big patch (3 files changed, 416 insertions(+), 237
deletions(-)), but the Linux patch was 13 files changed, 2,589
additions(+) and 2,195 deletions(-).

Original Linux commit log:
Change ntb_hw_intel to use the new NTB hardware abstraction layer.

Split ntb_transport into its own driver.  Change it to use the new NTB
hardware abstraction layer.
