DASH firmware runs on the APE side of the chip, but it requires a few MAC
to be programmed correctly.

When WOL is enabled and management firmware is disabled, incoming
packets are evaluated and discarded at the chip's rule processor.
When management firmware is enabled, the hardware must be informed that
there are agents further up the stack that still use the incoming
frames.  Normally management firmware will configure the MAC correctly
on its own, but there can be cases where the setting could get clobbered
by the driver.  The first hunk of this patch preserves this setting.

The second hunk of this patch wipes out the driver present signature of
the APE memory space.  By doing so, the DASH firmware can assume
driver absent behavior.

This patch replaces the existing APE register mapping code with a call
to pci_ioremap_bar().  The code that maps the main device register space
did not undergo a similar change because the information derived from
the pci_resource_start() and pci_resource_len() is still used to
populate the (optional) mem_start and mem_end netdevice members.
Replace hardcoded constants where appropriate.

This eliminates the following often-generated warning from my 64 bit
Opteron SMP test stand:

	eth0: too many iterations (6) in nv_nic_irq

According to the web, the problem is that the forcedeth driver has a
too-low value for max_interrupt_work.  Grepping the kernel I see that
forcedeth has the second lowest value of all ethernet drivers (ie, 6).
Most are in the 20-40 range.  So this patch increases this a bit, from 6
to 15 (at 15 forcedeth becomes the driver with third-lowest
max_interrupt_work value).

My test stand, which used to print out the above warnings repetitively
whenever it was under heavy net load, no longer does so.

After removing netem classful functionality we are sure its inner
qdisc is tfifo, so we can replace qdisc->ops->requeue() method with
open code. After this patch there are no more ops->requeue() users.

The idea of this patch is by Patrick McHardy.
Signed-off-by: NJarek Poplawski <jarkao2@gmail.com>
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Patrick McHardy noticed that: "a lot of the functionality of netem
requires the inner tfifo anyways and rate-limiting is usually done
on top of netem. So I would suggest so either hard-wire the tfifo
qdisc or at least make the assumption that inner qdiscs are
work-conserving.", and later: "- a lot of other qdiscs still don't
work as inner qdiscs of netem [...]".

So, according to his suggestion, this patch removes classful options
of netem. The main reason of this change is to remove ops->requeue()
method, which is currently used only by netem.

Corey Minyard spotted a missing memory barrier in udp_lib_get_port()

We need to make sure a reader cannot read the new 'sk->sk_next' value
and previous value of 'sk->sk_hash'. Or else, an item could be deleted
from a chain, and inserted into another chain. If new chain was empty
before the move, 'next' pointer is NULL, and lockless reader can
not detect it missed following items in original chain.

This patch is temporary, since we expect an upcoming patch
to introduce another way of handling the problem.

RFC4301 Section 7.1 says:

"7.1.  Tunnel Mode SAs that Carry Initial and Non-Initial Fragments

     All implementations MUST support tunnel mode SAs that are configured
     to pass traffic without regard to port field (or ICMP type/code or
     Mobility Header type) values.  If the SA will carry traffic for
     specified protocols, the selector set for the SA MUST specify the
     port fields (or ICMP type/code or Mobility Header type) as ANY.  An
     SA defined in this fashion will carry all traffic including initial
     and non-initial fragments for the indicated Local/Remote addresses
     and specified Next Layer protocol(s)."

But for IPv6, fragment is treated as a protocol.  This change catches
protocol transported in fragmented packet.  In IPv4, there is no
problem.

 each interrupt -this will help in debuging wme later)
*Some minor updates from legacy-hal
*Properly handle RXNOFRM and TXNOFRM interrupt masking (even when we don't set
 them on IMR they keep showing up, so we disable them by zeroing AR5K_RXNOFRM
 and AR5K_TXNOFRM registers). This doesn't exist on legacy-hal but i've tested
 it on various cards and it works fine.

This function has a few WARNs that may eventually trigger
when an AP sends rogue beacons, those must be removed. Some
of the comments in the function are also inappropriate as
this function is concerned with the global hint, not a per-
wiphy thing (which a multidomain flag on a wiphy would imply).

I'm convinced that we don't need to do anything to implement
multi-domain capability as 802.11-2007 specifies it because
it makes only two things mandatory:
 * starting of BSS/IBSS must have country information
   (this can easily be done with a mac80211 patch)
 * a STA must adopt the country information (we already have
   the framework for this)

But we don't have anything implemented anyway for now.
