ath9k: Fixed RX decryption status reporting
The RX code in ath9k uses sc_keymap to figure out whether a default
key was used. However, the default key entries in sc_keymap were
always set and as such, frames could have been claimed to be decrypted
by hardware when they were not. This can cause problems especially
with TKIP since mac80211 is validating the Michael MIC in the frame
and this will result in MIC failure and potentially TKIP
countermeasures if the frame was not decrypted correctly.
Change key cache slot allocation to mark only the keys that really
have been used in sc_keymap to avoid the issue. The key cache slot
selection routines are now internally avoiding the slots that may be
needed for TKIP group keys.

The timeout handling code is currently broken in several ways:
- It calls stop() (which frees all the memory and IRQ), and then
calls startup() (which won't re-request IRQ, neither it will
re-init the Fast UCC structure).
- It calls these routines from the softirq context, which is wrong,
since stop() calls free_irq() (which might sleep) and startup()
allocates things with GFP_KERNEL.
- It won't soft-reset the PHY. We need the PHY reset for at least
MPC8360E-MDS boards with Marvell 88E1111 PHY, the PHY won't recover
from timeouts w/o the reset.
So the patch fixes these problems by implementing the workqueue for the
timeout handling, and there we fully re-open the device via close() and
open() calls. The close/open paths do the right things, and I can see
that the driver actually survive the timeouts.

With this patch we'll wait the graceful stop for 100 ms, and then will
simply exit. There is nothing* we can do about that, but it's OK since
we'll do full reset later.
* Well, actually, there is also not-graceful variant for the TX stop,
but specs says that we never should use it.

NIU: Implement discard counters
Implementing discard counters for the NIU driver turned out to be more
complicated than first assumed.
The discard counters for the NIU neptune chip are only 16-bit (even
though this is a 64-bit chip). These 16-bit counters can overflow
quickly, especially considering this is a 10Gbit/s ethernet card.
The overflow indication bit is, unfortunatly, not usable as the
counter value does not wrap, but remains at max value 0xFFFF.
Resulting in lost counts until the counter is reset.
The read and reset scheme also poses a problem. Both in theory and in
practice counters can be lost in between reading nr64() and clearing
the counter nw64(). For this reason, the number of counter clearings
nw64() is limited/reduced. On the fast-path the counters are only
syncronized once it exceeds 0x7FFF. When read by userspace, its
syncronized fully.

enc28j60: reduce the number of spi transfers in enc28j60_set_bank()
A major source of overhead in the enc28j60 driver is the SPI transfers. Each
SPI transfer entails two kernel thread context switches. One major source of
SPI transfers is the enc28j60_set_bank() functions which runs before every
register access. This patch reduces the number of SPI transfers that
enc28j60_set_bank() performs in two ways:
1. removes unnecessary bank switch for the registers that are present in all
banks
2. when switching from banks 0 or 3 to banks 1 or 2 (i.e. only one bit
changes) enc28j60_set_bank() does only one SPI transfer instead of two
According to my tests these changes reduce the number of SPI transfers in
about 25%.

| netdevice zd1201: Convert directly reference of netdev->priv to netdev_priv()
|
| We have some reasons to kill netdev->priv:
| 1. netdev->priv is equal to netdev_priv().
| 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
| netdev_priv() is more flexible than netdev->priv.
| But we cann't kill netdev->priv, because so many drivers reference to it
| directly.
|
| OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
| and I want to kill netdev->priv later, I decided to convert all the direct
| reference of netdev->priv first.
|
| (Original patch posted by Wang Chen <wangchen@cn.fujitsu.com> w/ above
| changelog but using dev->ml_priv. That doesn't seem appropriate
| to me for this driver, so I've revamped it to use netdev_priv()
| instead. -- JWL)

the free method of it.
This causes "zd" be used after the memory, which is pointed by "zd", being

RFC3542:
6.7. Summary of Outgoing Interface Selection
This document and [RFC-3493] specify various methods that affect the
selection of the packet's outgoing interface. This subsection
summarizes the ordering among those in order to ensure deterministic
behavior.
For a given outgoing packet on a given socket, the outgoing interface
is determined in the following order:
1. if an interface is specified in an IPV6_PKTINFO ancillary data
item, the interface is used.
2. otherwise, if an interface is specified in an IPV6_PKTINFO sticky
option, the interface is used.

the the value seted with setsockopt() should be returned.

Issuing getsockopt() for the above options will return the sticky

net: Refactor full duplex flow control resolution
These 4 drivers have identical full duplex flow control resolution
functions. This patch changes them all to use one common function.
The function in question decides whether a device should enable TX and
RX flow control in a standard way (IEEE 802.3-2005 table 28B-3), so this
should also be useful for other drivers.

flags used within drivers for indicating tx and rx flow control are

The 3 SMSC drivers use the same constants (FLOW_CTRL_TX), but TG3 uses
TG3_FLOW_CTRL_TX, so this patch also renames the constants within TG3.

enc28j60: use netif_rx_ni() to deliver RX packets
The enc28j60 driver reads incoming packets in the process (workqueue) context,
not in a tasklet or the interrupt context. Thus, we should use netif_rx_ni()
to deliver those packets to the networking layer, instead of netif_rx(). This
way incoming packets don't wait in the incoming queue for the next IRQ to be
serviced.
