5b10ca19ea Mostly revert "e1000/e1000e: Move PCI-Express device IDs over to e1000e"
The new e1000e driver is apparently not yet suitable for general use, so
mark it experimental, and re-instate all the PCI-Express device IDs in
the old and stable e1000 driver so that people (namely me) can continue
to use a driver that actually works.

Auke & co have been appraised of the situation.

c0e1899bdb ath5k: always extend rx timestamp with tsf
always extend the rx timestamp with the local TSF, since this information is
also needed for proper IBSS merging. this is done in the tasklet for now, maybe
has to be moved to the interrupt handler like in madwifi.

6d91e1d808 ath5k: configure backoff for IBSS beacon queue
in "11.1.2.2 Beacon generation in an IBSS" the IEEE802.11 standard says, each
STA should... "b) Calculate a random delay uniformly distributed in the range
between zero and twice aCWmin × aSlotTime,".

configure cwmin and cwmax of the beacon queue in IBSS mode according to this.
unfortunately beacon backoff does not work reliably yet, so i suspect we have a
problem somewhere else, since the same settings (and similar beacon timer
configuration) work for madwifi.

036cd1ec03 ath5k: use SWBA to detect IBSS HW merges
use SWBA (software beacon alert) interrupts to keep track of the next beacon
time und check if a HW merge (automatic TSF update) has happened on every
received beacon with the same BSSID.

this is necessary because the atheros hardware will silently update the local
TSF in IBSS mode, but not its beacon timers. if the TSF is ahead of the beacon
timers no beacons are sent until the timers wrap around (typically after about
1 minute).

this solution is not very nice, since we have to look into every beacon, but
there is apparently no other way to detect HW merges.

9804b98d57 ath5k: better beacon timer calculation
update ath5k_beacon_update_timers() for better beacon timer calculation in a
variety of situations. most important is the possibility to call it with the
timestamp of a received beacon, when we detected that a HW merge has happened
and we need to reconfigure the beacon timers based on that.

we call this from the mac80211 callback reset_tsf now instead of beacon_update,
and there will be more use of it in the next patch.

1f7d87b0ec b43: Fix MAC control and microcode init
This zeros out all microcode related memory before loading
the microcode.

This also fixes initialization of the MAC control register.
The _only_ place where we overwrite the contents of the MAC control
register is at the beginning of b43_chip_init().
All other places must do read() -> mask/set -> write() to not
overwrite existing bits.

This also adds a longer delay for waiting for the microcode
to initialize itself. It seems that the current timeout is sufficient
on all available devices, but there's no real reason why we shouldn't
wait for up to one second. Slow embedded devices might exist.
Better safe than sorry.

9d5c824399 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.

e655b9f03f iwlwifi: fix problem when rf_killswitch change during suspend/resume
After we delay device initialization until interface up, there are more
conditions for the hardware rf_kill switch states during suspend and
resume. For example, before suspend we can have interface up or down,
rf_kill enable or disable; before resume we can have rf_kill enable or
disable. So there are totally 2^3 = 8 conditions to handle. This patch
addressed this problem and makes sure every condition works correctly.

This patch also merges the device suspend and resume handlers with the
mac_start and mac_stop code since they are basically doing the same
thing.

5a66926aa9 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
upon the first version.
