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.

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.

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

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.

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.

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.

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.

The packet filter flags don't belong in the interface structure
because they are device based instead of interface based.
So move the filter fields out of struct interface and into rt2x00_dev.
Additionally we shouldn't change the filter based on the working
mode, if such a thing is needed than mac80211 should have done that.

suspend & resume was broken since it called rt2x00mac_start()
and rt2x00mac_stop() which would fail to execute because the
DEVICE_PRESENT flag was not set.
Move the start and stop handlers into rt2x00lib.c which are called
from rt2x00mac_start() and rt2x00mac_stop() after they have checked
the DEVICE_PRESENT flag, while suspend and resume handlers can
directly call those functions.

These flags used to be fixed to one in rt2500pci_config_type, which
caused the beacon timer interrupt to fire. This would lead to
rt2x00lib_beacondone adding work which called
rt2x00lib_beacondone_scheduled which called ieee80211_beacon_get which
printed an error about not having any beacon data.
With this patch, these interrupts are only generated when the interface
is configured to send beacons.

Apparently it was possible that ieee80211_stop_queue() was not full while
NETDEV_TX_BUSY was being reported back. I think that is what causing the WARN_ON().
This moves all calls to ieee80211_stop_queue() in rt2x00mac.c where it is easier
to determine if the queue should be halted.

This adds a new Kconfig option for enabling probing of N-PHYs.
This option will be removed again once the stuff works.
For now it is to help in development. This way real users won't
execute the broken N-PHY codepaths, but the developers can easily
enable N-PHY stuff.
To enable N-PHY probing simply remove the BROKEN dependency
and enable the option in the kernel config.

Reviewing the semaphore usage I noticed these down_interruptible calls. Most

* back in 2.3.20 driver got readb() and friends instead of
direct dereferencing of iomem. Somebody got too enthusiatic and replaced
ntohs(p->mrx_overflow)
with
ntohs(read(&p->mrx_overflow)
without noticing that (a) the sucker is 16bit and (b) that expression can't possibly
be portable anyway (hell, on l-e it's always less than 256, on b-e it's always a
multiple of 256). Proper fix is
swab16(readw(&p->mrx_overflow)
taking into account the conversion done by readw() itself. That crap happened
in several places; the same fix applies.
