* 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
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.
This commit adds support for MDIO present in the ThunderX SoC.
From the FDT point of view it is compatible with "octeon-3860-mdio"
however only C22 mode is used.
The code also implements lmac_if interface functions.

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.

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.

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).

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.

Still part of the huge e26a5843 rewrite. I'm trying to make it less of

interrupt controller.
The latter is required for INTRNG, because of the hardware erratum
workaround installed by the linux folks into the imx6 FDT data, which remaps
an ethernet interrupt to the gpio device. In the non-INTRNG world we
intercept the call to map the interrupt and map it back to the ethernet
hardware (because we don't need linux's workaround), but in the INTRNG world
we lose the hookpoint where that remapping was happening, but we gain the
ability to work the way linux does by having the gpio driver dispatch the
interrupt.

and armv6 architecures. The primary enhancement over the old design is
support for hierarchical interrupt controllers (such as a gpio driver
which can receive interrupts from a root PIC and act as a PIC itself for
clients interested in handling a change of gpio pin state as an
interrupt). The new code also provides an infrastructure for mapping
interrupts described in metadata in the form of a "controller reference
plus interrupt number" tuple into the simple "0-n" flat numeric space
understood by rman and the bus resource mechanisms.
Use of the new code is enabled by setting the ARM_INTRNG option, and by
making a few simple changes to the platform's support code. In addition
each existing PIC driver needs changes to be ready for INTRNG; this commit
contains the changes for the arm/gic driver, which most armv6 SoCs use, but
it does not enable the new code yet on any platform.
This project has been many years in the making, starting as a GSoC project
by Jakub Klama (jceel@) in 2012. That didn't get committed right away and
the source base evolved out from under it to some degree. In 2014 I rebased
the diffs to then -current and did some enhancements in the area of mapping
interrupt numbers and storing associated fdt data, then the project went
cold again for a while. Eventually Svata Kraus took that work in progress
and did another big round of work on it, removing most of the remaining
rough edges. Finally I took that and made one more pass through it, mostly
disabling the "INTR_SOLO" feature for now, pending further design
discussions on how to most efficiently dispatch a pending interrupt through
more than one layer of PIC. The current code with the INTR_SOLO feature
disabled uses approximate 100 extra cpu cycles for each cascaded PIC the
interrupt has to be passed to, so what's left to do is about efficiency, not
correct operation.

causing some userland applications to crash. A workaround was committed in
r284707 where userland would check if the aux vector was passed using the
old or new ABI and adjust the stack if needed. As 4 months have passed it
is time to move to the new ABI, with the expectation the compat code in csu
and the runtime linker to be removed in the future.
