This includes the following:
- use separate memory regions for VALE ports
- locking fixes
- some simplifications in the NIC-specific routines
- performance improvements for the VALE switch
- some new features in the pkt-gen test program
- documentation updates
There are small API changes that require programs to be recompiled
(NETMAP_API has been bumped so you will detect old binaries at runtime).
In particular:
- struct netmap_slot now is 16 bytes to support an extra pointer,
which may save one data copy when using VALE ports or VMs;
- the struct netmap_if has two extra fields;

Then, as part of this, convert a couple of mbuf m->m_data accesses
to mtod(m, const void *).

Use the published compatible strings (our own invention, "ti,mmchs" is
still accepted as well, for now).
Don't blindly turn on 8-bit bus mode, because even though the conroller
supports it, the board has to be wired appropriately as well. Use the
published property (bus-width=<n>) and honor all the valid values (1,4,8).
The eMMC device on a Beaglebone Black is wired for 8-bit, update the dts.
The mmchs controller can inherently do both 1.8v and 3.0v on the first
device and 1.8v only on other devices, unless an external transceiver is
used. Set the voltage automatically for the first device and honor
the published fdt property (ti,dualvolt) for other devices.
Thanks go to Ilya Bakulin for figuring out the voltage compatibility stuff.
Note that svn 257268 gnu/usr.bin/binutils/ld/Makefile
seems to break the "toolchain" target when building HEAD
on RELENG_9, so until this is solved you may want to

Right now, the semaphore write is scheduled after each batch, which is

This is useful if you somehow messup pkg(8) and need to reinstall from
remote with it already being registered in the pkg(8) /var/db/pkg database.
Also add some sanity checks to 'pkg add'.

already used on-stack temporary storage, so just use it more rationally.
getenv_string() receives buffer as argument, so don't need another one.
The imx6.dtsi is incomplete, but has enough to support devices that work

account for the differences between SoCs in the imx6 family.

and simplify/adjust accordingly.
Note that with this change the defaults of the ptc.e parameters
have changed. Since all hardware is supposed to support the PAL
call, there should be no impact. Even ski is unaffected, because
the TC is re-initialized without considering the virtual address.
So, as long as we call ptc.e at least once, we're good. That's
what the new defaults do.
Most processor implementations need but a single ptc.e to purge
the entire TC anyway...
end, make pmap_invalidate_all() global and have it only handle the
local CPU -- i.e. no rendezvous. We do not use pmap_invalidate_all
other than during initialization.
Note that the BSP already purges its TC -- it was missing for APs
only. Nonetheless, this so far seems to eliminate random problems.
ia64_probe_sapics(), we also create PCPU structures for any Local SAPICs
we encounter. When SMP is disabled, this leaves us with partially setup
PCPU structures, which typically results in panics when we're iterating
over CPUs. When SMP is disabled, we now prevent the creation of the
PCPU structures.
Unexpand the tag, remove the fbsd:nokeywords property and add the
svn:keywords property. This should eliminate the gratuituous diffs
that appear on these files in projects branches.

and ordering related variables, fields and locks next to each
other. Add more comments to variables.
Over time 'ifnet' has accumlated a lot of additional pointers and
functionality in an unstructured way making it quite hard to read
and understand while obfuscating relationships between fields and
variables.
Quantify the structure size and how bloated it has become.
This is only a mechanical change in preparation for upcoming
work to make ifnet opaque to drivers and to separate out the
interface queuing.

CDC=0 simply means "no command codes", CDC=1 means "AT command codes."
There's no driver change required! It's purely to tell the application
layer whether to speak AT commands or not. Things are all still serial.
