igb: PCI-Express 82575 Gigabit Ethernet driver
We are pleased to announce a new Gigabit Ethernet product and its
driver to the linux community. This product is the Intel(R) 82575
Gigabit Ethernet adapter family. Physical adapters will be available
to the public soon. These adapters come in 2- and 4-port versions
(copper PHY) currently. Other variants will be available later.
The 82575 chipset supports significantly different features that
warrant a new driver. The descriptor format is (just like the
ixgbe driver) different. The device can use multiple MSI-X vectors
and multiple queues for both send and receive. This allows us to
optimize some of the driver code specifically as well compared to
the e1000-supported devices.
This version of the igb driver no lnger uses fake netdevices and
incorporates napi_struct members for each ring to do the multi-
queue polling. multi-queue is enabled by default and the driver
supports NAPI mode only.
All the namespace collisions should be gone in this version too. The
register macro's have been condensed to improve readability.

iwlwifi: delay firmware loading from pci_probe to network interface open
This patch moves the firmware loading (read firmware from disk and load
it into the device SRAM) from pci_probe time to the first network
interface open time. There are two reasons for doing this:
1. To support kernel buildin iwlwifi drivers. Because kernel initializes
network devices subsystem before hard disk and SATA subsystem, it is
impossible to get the firmware image from hard disk in the PCI probe
handler. Thus delaying the firmware loading into the network
interface open time is the way to go. Note, we only read the firmware
image from hard disk the first time the interface is open. After this
is succeeded, we cache the firmware image into the host memory. This
is a performance gain when user open and close the interface multiple
times and is necessary for device suspend and resume.
2. For better power saving. When the iwlwifi modules are loaded (or
buildin the kernel) but the wireless network interface is not being
used, it is a good practice the wireless device consumes as less
power as possible. Unloading the firmware from the wireless device
and unregister the driver's interrupt handler in the network
interface close handler provides users a way to achieve this. User
space network configuration tools (i.e NetworkManager) can also
contribute here when it detects a wired cable is connected and
close the wireless interface automatically.
This patch also includes the pci_save/restore_state() fixed by Ian Schram

This patch fixes an oops which was introduced as a regression by
commit fd640775bd16e1df50c867cc547af0, on the patch titled,
"mac80211: dont use interface indices in drivers".
ieee80211_generic_frame_duration() now relies on sdata->flags which
itself gets set upon bringing the interface up. We check for the
virtual interface now before setting the rate duration registers.
After the mode changes are introduced onto mac80211 we should revisit
these changes.
This patch was tested on the following cards:
1) BG card:
Atheros AR5213A chip found (MAC: 0x59, PHY: 0x43)
RF2112A 2GHz radio found (0x46)
2) ABG card:
Atheros AR5213A chip found (MAC: 0x59,PHY: 0x43)
RF5112A multiband radio found (0x36)

mac80211: add beacon configuration via cfg80211
This patch implements the cfg80211 hooks for configuring beaconing
on an access point interface in mac80211. While doing so, it fixes
a number of races that could badly crash the machine when the
beacon is changed while being requested by the driver.

mac80211: move interface type to vif structure
Drivers that support mixed AP/STA operation may well need to
know the type of a virtual interface when iterating over them.
The easiest way to support that is to move the interface type
variable into the vif structure.

mac80211: dont use interface indices in drivers
This patch gets rid of the if_id stuff where possible in favour of
a new per-virtual-interface structure "struct ieee80211_vif". This
structure is located at the end of the per-interface structure and
contains a variable length driver-use data area.
This has two advantages:
* removes the need to look up interfaces by if_id, this is better
for working with network namespaces and performance
* allows drivers to store and retrieve per-interface data without
having to allocate own lists/hash tables

Add rtl8180 wireless driver
This patch adds a mac80211 based wireless driver for the rtl8180 and
rtl8185 PCI wireless cards. Also included are some rtl8187 changes
required due to the relationship between that driver and this one.
Michael Wu is primarily responsible for the initial driver and rtl8185
support. Andreas Merello provided the additional rtl8180 support.
Thanks to Jukka Ruohonen for the donating a rtl8185 card! It was very
helpful for the rtl8225z2 code.
