97bba30626 Apply a few small optimizations to boot2's code, to make it shrink a
little further.  This gets us further on the way to be able to build it
successfully with clang.  Using in-tree gcc, this shrinks boot2.bin with
60 bytes, the in-tree clang shaves off 72 bytes, and ToT clang 84 bytes.

f6ff7180f8 Fix a regression introduced in r215906. The change made in r215906
caused link re-negotiation whenever application joins or leaves a
multicast group.  If driver is running, it would have established a
link so there is no need to start re-negotiation. The re-negotiation
broke established link which in turn stopped multicast application
working while re-negotiation is in progress.

56bdf2dbc2 Since r218070 reenabled the call to vm_map_simplify_entry() from
vm_map_insert(), the kmem_back() assumption about newly inserted
entry might be broken due to interference of two factors. In the low
memory condition, when vm_page_alloc() returns NULL, supplied map is
unlocked. If another thread performs kmem_malloc() meantime, and its
map entry is placed right next to our thread map entry in the map,
both entries wire count is still 0 and entries are coalesced due to
vm_map_simplify_entry().

Mark new entry with MAP_ENTRY_IN_TRANSITION to prevent coalesce.
Fix some style issues, tighten the assertions to account for
MAP_ENTRY_IN_TRANSITION state.

67c1af9d00 Correct a subtle bug in the 'gsched_rr' disk scheduler.
The algorithm is supposed to work as follows:
in order to prevent starvation, when a new client starts being served we
record the start time and reset the counter of bytes served.
We then switch to a new client after a certain amount of time or bytes,
even if the current one still has pending requests.
To avoid charging a new client the time of the first seek,
we start counting time when the first request is served.

Unfortunately a bug in the previous version of the code failed
to set the start time in certain cases, resulting in some processes
exceeding their timeslice.

The fix (in this patch) is trivial, though it took a while to find
out and replicate the bug.
Thanks to Tommaso Caprai for investigating and fixing the problem.

f0ecc46d04 Add support for the new I350 family of 1G interfaces.
- 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!!

529844c77c Linux' shm_open() fails because it wants to find some funky shmfs
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.

278e79707e Provide convenience function for obtaining MODINFO_ADDR and MODINFO_SIZE

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).

e7d14e9bcc Rework beacon handling re-enable run_updateslot().
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.

67397d396f Add in the (very!) optional glue to flip the 11n bits for if_ath.
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.)

be97670785 Fix the keycache behaviour for multicast keycache search.
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.

So, in preparation for addressing this workaround, (re)-expose the particular

boundary transactions or not.

A subsequent commit will modify the descriptor allocation to avoid allocating
descriptor entries that straddle a 4k page boundary.

e7ceb1e99b Based on discussions on the svn-src mailing list, rework r218195:
- entirely eliminate some calls to uio_yeild() as being unnecessary,

 - move should_yield() and maybe_yield() to kern_synch.c and move the
   prototypes from sys/uio.h to sys/proc.h

 - add a slightly more generic kern_yield() that can replace the
   functionality of uio_yield().

 - replace source uses of uio_yield() with the functional equivalent,
   or in some cases do not change the thread priority when switching.

 - fix a logic inversion bug in vlrureclaim(), pointed out by bde@.

 - instead of using the per-cpu last switched ticks, use a per thread
   variable for should_yield().  With PREEMPTION, the only reasonable
   use of this is to determine if a lock has been held a long time and
   relinquish it.  Without PREEMPTION, this is essentially the same as
   the per-cpu variable.

a07e9ddb3b Just tag all RX packets as needing reorder processing for now.
This fixes two problems -

* All packets need to be processed here, not just aggregate ones - as any
  received frames (AMPDU or otherwise) in the given TID (traffic class id)
  will update the sequence number and, implied with that, update the window;
* It seems there's situations where packets aren't matching a current node but
  somehow need to be tracked. Thus just tag them all for now; I'll figure out
  the why later.

Whilst I'm here, bump the stats counters whilst I'm at it.

This fixes AMPDU RX in my tests; the main problems now stem from what look
like PHY level error/retransmits which are impeding general throughput, incl.
AMPDU.
