actual napi_struct is exposed in the ieee80211_hw structure so that the

this the device operates at a power level which only conforms to the

The regulatory limit by CRDA is always used but does not provide

Using the calibrated data from the EEPROM ensures the device
operates at optimal output power while still ensuring proper

tx timestamping, which needs the sk-reference in the skb on driver level.
So does the can-raw socket, which has not been taken into account here.
The patch below adds a 'prevent_sk_orphan' bit in the skb tx shared info,
which fixes the problem discovered by Matthias Fuchs here:
http://marc.info/?t=
128030411900003&r=1&w=2
Even if it's not a primary tx timestamp topic it fits well into some skb
shared tx context. Or should be find a different place for the information to
protect the sk reference until it reaches the driver level?

Revert "net: remove zap_completion_queue"
This reverts commit
15e83ed78864d0625e87a85f09b297c0919a4797.
As explained by Johannes Berg, the optimization made here is
invalid. Or, at best, incomplete.
Not only destructor invocation, but conntract entry releasing
must be executed outside of hw IRQ context.
So just checking "skb->destructor" is insufficient.

As pm_qos changed to use plists there is no benefit in registering and

tg3: Improve small packet performance
smp_mb() inside tg3_tx_avail() is used twice in the normal
tg3_start_xmit() path (see illustration below). The full memory
barrier is only necessary during race conditions with tx completion.
We can speed up the tx path by replacing smp_mb() in tg3_tx_avail()
with a compiler barrier. The compiler barrier is to force the
compiler to fetch the tx_prod and tx_cons from memory.
In the race condition between tg3_start_xmit() and tg3_tx(),
we have the following situation:
tg3_start_xmit() tg3_tx()
if (!tg3_tx_avail())
BUG();
...
if (!tg3_tx_avail())
netif_tx_stop_queue(); update_tx_index();
smp_mb(); smp_mb();
if (tg3_tx_avail()) if (netif_tx_queue_stopped() &&
netif_tx_wake_queue(); tg3_tx_avail())
With smp_mb() removed from tg3_tx_avail(), we need to add smp_mb() to
tg3_start_xmit() as shown above to properly order netif_tx_stop_queue()
and tg3_tx_avail() to check the ring index. If it is not strictly
ordered, the tx queue can be stopped forever.
This improves performance by about 3% with 2 ports running
bi-directional 64-byte packets.

netfilter: nf_nat: don't check if the tuple is unique when there isn't any other choice
The tuple got from unique_tuple() doesn't need to be really unique, so the
check for the unique tuple isn't necessary, when there isn't any other
choice. Eliminating the unnecessary nf_nat_used_tuple() can save some CPU
cycles too.

The only user of unique_tuple() get_unique_tuple() doesn't care about the
return value of unique_tuple(), so make unique_tuple() return void (nothing).

ipvs: remove EXPERIMENTAL tag
IPVS was merged into the kernel quite a long time ago and
has been seeing wide-spread production use for even longer.
It seems appropriate for it to be no longer tagged as EXPERIMENTAL

netfilter: {ip,ip6,arp}_tables: dont block bottom half more than necessary
We currently disable BH for the whole duration of get_counters()
On machines with a lot of cpus and large tables, this might be too long.
We can disable preemption during the whole function, and disable BH only
while fetching counters for the current cpu.
