Add the VNET_ASSERT() to the non-VNET_DEBUG case as well so that
INVARIANTS will still catch problems.

Make VNET_ASSERT() available with either VNET_DEBUG or INVARIANTS.
Change the syntax to match KASSERT() to allow more flexible panic
messages rather than having a printf with hardcoded arguments
before panic.
Adjust the few assertions we have to the new format (and enhance
the output).

seem to work when building xdev anymore (most likely my changes lately
moving the TARGET guessing stuff to Makefile from Makefile.inc1, but I
really don't grok why). Fix make xdev by putting them on the command
line. This will work either way while I try to figure it out.
make sure we define it for the xdev stuff.
Move xdev stuff to be last again in this file.
# xdev-build works now, but xdev-install appears to be broken though.
- this also includes virtualization support on these devices
Correct some vlan issues we were seeing in test, jumbo frames on vlans
did not work correctly, this was all due to confused logic around HW
filters, the new code should now work for all uses.
Important fix: when mbuf resources are depeleted, it was possible to
completely empty the RX ring, and then the RX engine would stall
forever. This is fixed by a flag being set whenever the refresh code
fails due to an mbuf shortage, also the local timer now makes sure
that all queues get an interrupt when it runs, the interrupt code
will then always call rxeof, and in that routine the first thing done
is now to check the refresh flag and call refresh_mbufs. This has been
verified to fix this type 'hang'. Similar code will follow in the other
drivers.
Finally, sync up shared code for the I350 support.
Thanks to everyone that has been reporting issues, and helping in the
debug/test process!!

Some of the patches we are preparing for porting ATF from NetBSD
refer to '/usr/libexec' several times. Instead of repeating the
path all over the place, add ${LIBEXECDIR} to match ${LIBDATADIR}

to construct the full pathname. It starts to search at the default
mountpoint which is /dev/shm. If this fails it runs through fstab
and searches for shmfs and tmpfs. Whatever it finds will be
statfs()'ed to be checked for Linux' fs magic for shmfs (0x01021994).
Ideally our tmpfs should deliver this fs magic to Linux processes, but
as our tmpfs is considered to be an experimental feature we can not
assume that there is always a tmpfs available.
To make shared memory work in the Linuxulator, force the fs type of
/dev/shm (which can be a symlink) to match what Linux expects. The user
is responsible (info has to be added to the linux base ports and the docs)
to setup a suitable link for /dev/shm.

attributes for preloaded modules/images. In particular, MODINFO_ADDR has
the added complexity of not always being relocated properly. Rather than
kluging this in the various components that are affected, we handle it
in a centralized place (preload_fetch_addr()). To that end, expose a new
variable, preload_addr_relocate, that MD initialization code can set and
that turns the address attribute into a valid kernel VA.
Architectures that need the relocation: arm & powerpc (at least).
Components that can utilize this: acpi(4), md(4), fb(4), pci(4), ZFS, geli.

Drivers which rely on net80211 to create the beacon need to call
ieee80211_beacon_update() on iv_update_beacon() calls. This is required
that certain bits, e.g. TIM, get updated. A call to ieee80211_beacon_alloc()
is not enough because it does not care about flags which can only change
during runtime. By design a beacon is supposed to be allocated only once
while moving into RUN state.
To handle all possible calls to iv_update_beacon() the run_updateslot()
function has been revived and run_updateprot() has been added.
run_updateslot() handles slot time changes and run_updateprot() changes
to protection, both can change while nodes associate/leave.

There's still a lot of random issues to sort out with the radio side of
things and AMPDU RX handling (and completely missing AMPDU TX handling!)
but if people wish to give this a go and assist in debugging the
issues, they can define ATH_DO_11N to enable it.
I'm just re-iterating - this is here to allow people to assist in
further 11n development; it is not any indication that the 11n support
is complete and functional.
Important notes:
* This doesn't support 1-stream cards yet - (eg AR9285) - the various bits
that negotiate TX/RX MCS don't know not to try >1 stream TX or negotiate
1-stream RX; so don't enable 11n unless you've first taught the rate
control module and the net80211 stack to negotiate 1-stream stuff;
* The only rate control module minimally 11n aware is ath_rate_sample;
* ath_rate_sample doesn't know about HT/40; so airtime will be incorrectly
calculated;
* The AR9160 and AR9280 radio code is unreliable at the higher MCS rates for
some reason; this will definitely impact 11n performance;
* AMPDU-TX isn't yet implemented;
* AMPDU-RX may be a bit buggy still and will definitely suffer from the
radio unreliability mentioned above (ie, don't expect 150/300mbit
RX just yet.)
SU+J is not included as a FEATURE macro:
- it was not in the tree during the GSoC
- I do not see an option to en-/disable it in NOTES
Two minor changes where made during the review compared to what was developed
during GSoC 2010.
No FreeBSD version bump, the userland application to query the features will
be committed last and can serve as an indication of the availablility if
needed.

The correct bit to set is 0x1 in the high MAC address byte, not 0x80.
The hardware isn't programmed with that bit (which is the multicast
adress bit.)
The linux ath9k keycache code uses that bit in the MAC as a "this is
a multicast key!" and doesn't set the AR_KEYTABLE_VALID bit.
This tells the hardware the MAC isn't to be used for unicast destination
matching but it can be used for multicast bssid traffic.
This fixes some encryption problems in station mode.
