Current code for the RTL8187 is not returning valid retry information, thus the
rate-setting mechanism is not functioning. As a further complication, this info
is only obtained by reading a register, which cannot be read while in interrupt
context.
This patch implements the TX status return to mac80211 through the use of a
work queue.
One additional problem is that the driver currently enables the rate fallback
mechanism of the device, which conflicts with the mac80211 rate-setting
algorithm. This version of the patch disables rate fallback.

if_cs_poll_while_fw_download() returned the number of iterations
remaining on success, which in turn got returned as the value from
if_cs_prog_real() and if_cs_prog_helper(). But since if_cs_probe()
interprets non-zero return values from firmware load functions as an
error, this sometimes caused spurious firmware load failures.

With mac80211 handling all open interfaces during

within rt2x00lib.
The only thing rt2x00 needs to do is free up memory
during suspend and bring back the minimal required

Now that cfg80211 has its own regulatory infrastructure we can
condense ath9k's regulatory code considerably. We only keep data
we need to provide our own regulatory_hint(), reg_notifier() and
information necessary for calibration.
Atheros hardware supports 12 world regulatory domains, since these
are custom we apply them through the the new wiphy_apply_custom_regulatory().
Although we have 12 we can consolidate these into 5 structures based on
frequency and apply a different set of flags that differentiate them on
a case by case basis through the reg_notifier().
If CRDA is not found our own custom world regulatory domain is applied,
this is identical to cfg80211's except we enable passive scan on most
frequencies.

The ath5k driver didn't use set_rts_threshold or use_cts_prot, and also

Tell the hardware about these so RTS/CTS will work, and so the device

1- make sure we are calling iwl3945_apm_reset and iwl3945_apm_stop

2- make sure we set CSR_GP_CNTRL_REG_FLAG_INIT_DONE in apm_reset before

Currently iwlagn is not able to report hw-killswitch events while the
interface is down. This has implications on user space tools (like
NetworkManager) relying on rfkill notifications to bring the interface
up once the wireless gets enabled through a hw killswitch.
Thus, enable the device already in iwl_pci_probe instead of iwl_up
and enable interrups while the interface is down in order to get
notified about killswitch state changes. The firmware loading is still
done in iwl_up.
