The Linux driver sets the rate_n_flags regardless of whether it's being
sent using firmware rate control or local rate control. This includes
the antenna configuration.
Thanks to Kyle Evans <kevans91@ksu.edu> for pointing this out to me
and doing some investigation/testing on his end.
Tested:
* Intel 7260 STA, 2G and 5G networks
64-bit MIPS, use superpage rather than physical-segment constants, or
we may improperly fail to apply suitable alignment -- yet still allow
mmap() to appear to succeed.

however after the timer has been probed it will switch to a more accurate

This is currently only a code change without any functional
change. But this allows to set the remote encapsulation port
in a more detailed way, which will be provided in a follow-up
commit.

FDT overlays is de-facto standard for describing expansion boards like
Beaglebone capes or Raspberry Pi shields. The ides is to have basic
DTB for base board and overlays DTB for shields/capes and to construct
final DTB either using human-readable configuration or some
self-discovery mechanism. I believe this approach can also be expanded
to support dynamically loadable FPGA bitstreams on systems like
Zedboard/Zybo.
Overlaying process is simmilar to executable link process for
binaries: each DTB has "exported" symbols and "undefined" symbols, the
latter are resolved using information for the former obtained from
base DTB or one of the overlays applied earlier (more rare case).
This symbols information is not generated by standard dtc that FreeBSD
has in base system, patched[1] version required to produces
overlay-compatible blobs. So although DTB files generated by
buildkernel do not support overlays there are enough
vendor/community-provided DTB blobs ciruclating around to justify
committing this change to ubldr.
This commit introduces handler for "fdt_overlays" variable that can be
defined either as a loader env variable or U-Boot env variable.
fdt_overlays is comma-separated list of .dtbo files located in
/boot/dtb/ directory along with base .dtb. ubldr loads files and
applies them one-by-one to base .dtb and then passes result blob to
the kernel.

clear vd->vdev_tsd in vdev_geom_close_locked instead of vdev_geom_detach.
In the latter function, it would fail to happen in certain circumstances
where cp->private was unset. Ideally, the latter should never happen, but
it can happen when vdev open fails, or where spares are involved.

This change adds few methods for net80211 channel table setup:
- ieee80211_add_channel()
- ieee80211_add_channel_ht40()
(primarily for drivers, that parse EEPROM to get channel list -
they will allow to hide implementation details).
- ieee80211_add_channel_list_2ghz()
- ieee80211_add_channel_list_5ghz()
(mostly as a replacement for ieee80211_init_channels() - they will allow
to specify non-default channel list; may be used in ic_getradiocaps()).
Tested with wpi(4) (add_channel) and rum(4) (add_channel_list_2ghz).

Split ADC driver in two halves: ADC(analog ot digital) and
TSC(touchscreen). Touchscreen driver is fully functional
up to the point of reporting samples. This part will be added
once FreeBSD has API for touchscreen.

I .. can't believe I missed this.
This showed up because the AP was TX'ing LDPC to an iwm(4) chipset,
which didn't advertise LDPC and doesn't /accept/ LDPC. Amusingly, all
the two other FreeBSD 11n parts I had tested with (AR9380, Intel 7260)
and I completely forgot to test on ye olde hardware.
That'll teach me.
Tested:
* AR9580 (AP) - Intel 7260 (STA), AR9380 (STA), Intel 6205 (STA)
This is a follow-up to r298789, which removed the B_DIRTY and B_PERSISTENT
flags. This changeset removes them from the associated %b bit description
string as well.
