* Add a tunable to enable 11n if it's available, so to not anger people
who upgrade.
kenv hw.usb.rsu.enable_11n=1 before inserting the device.
* Add initial 11n htconfig bits;
* Enable 40MHz mode if it's available;
* Add 11n channels;
* Set 11n bits in the firmware.
It works for RX; I haven't tested TX aggregation just yet.
However the firmware doesn't do RX re-ordering, so I have to tie it into
the net80211 A-MPDU RX reorder path before I flip this on by default.
I've verified that I'm indeed actually seeing MCS 0->7 rates being received.
I haven't dug into whether it's actually transmitting 11n rates; I'll dig into
that later.
with a reference count of zero can't possibly be mapped, so there is never a
need for vm_page_set_invalid() to call pmap_remove_all() on them.

Also note that these env-only vars can be specified on the command line.
This fixes the dependent options that are env-only (such as WITH_META_MODE
and WITH_AUTO_OBJ) to properly display their dependencies.

hold the kernel, modules, and any other loaded data. This memory block
is relocated to the kernel's expected location during the transfer of
control from the loader to the kernel.
The GENERIC kernel on amd64 has recently grown such that a kernel + zfs.ko
no longer fits in the default staging size. Bump the default size from
32MB to 48MB to provide more breathing room.

/sbin/route has a bug where if it is passed an interface name that does
not exist, it falls through and winds up interpreting it as a hostname.
It fails out eventually, but on a system where DNS lookup is broken you
can end up waiting for up to 60 seconds waiting for the DNS lookup to
timeout. I'm not quite sure what happens if the DNS lookup somehow
succeeds but I doubt that can end well.

r284708 addressed this slightly but seems to have put the make(showconfig)
guard in the wrong place. Rather than guard setting the default obj directory,
guard inclusion of auto.obj.mk. This avoids creating SRCTOP/obj and
SRCTOP/release/obj when running makeman.

This is relevant for makeman using the 'make targets' output in src.conf(5).
This makes a _UNIVERSE_TARGETS that removes arm64 if the build
requirements are not met.
* the tx descriptor TID is priority, not TID.
* the tx descriptor queue id mapping is separate from the

TODO:
* go and re-re-re-verify the queue mappings; the linux and openbsd

before I try to flip on 11n RX.
This avoids easily colliding multiple src trees with the same objects. Having
multiple checkouts in dir/ dir2/ dir3/ would all use obj/ without any unique
identifier inside of obj/. This pattern is more likely to be used due
to the non-META_MODE behavior working with it fine.
In environments where ../obj/ is wanted as the obj directory the value of
OBJROOT can be set to ${SRCTOP:H}/obj/ instead via src-env.conf (set by
SRC_ENV_CONF) or environment. For environment it must be single quoted or
escaped. This will be more likely for vendors who are building images or using
NFS for builds. In those cases MAKEOBJDIRPREFIX may already be utilized and
is supported.

The preferred way to modify the object directory root is to use OBJROOT.
However, setting OBJROOT to ${MAKEOBJDIRPREFIX}/${SRCTOP}/ effectively behaves
as expected.
The problem with this before was that setting OBJROOT to contain SRCTOP
resulted in a recursive replacement (/usr/obj/usr/obj/usr/src/). Anchoring to
the start of the path for replacing SRCCTOP in CURDIR resolves this by
avoiding replacing SRCTOP when CURDIR is within the OBJDIR.

* Do 1T1R for now, until we read the config out of ROM and use it.
* Disable turbo mode, I dunno what this is, but the linux drivers
have this disabled.
* Set the firmware endpoints to what we read from USB.
Tested:
* RTL8712 cut 3, STA mode
data queues.
This is similar to the openbsd and rtlwifi/r92su drivers.
Note: this driver still assumes it's a 4-endpoint device; I'll enforce
that in a follow-up commit.
Due to the use of int's for file offsets in the VOP_WRITE_(PRE|POST)
macros, kqueue write events for files greater 2GB where never fired.
This caused tail -f on a file greater 2GB to never see updates.
