ath: add support for special 0x8000 regulatory domain

2009-07-21T19:59:50+00:00

Two users of ar9170 devices have now reported their cards
have been programmed with a regulatory domain of 0x8000.
This is not a valid regulatory domain as such these users were
unable to use these devices. Since this doesn't seem to be
a device EEPROM corruption we must treat it specially. It
may have been possible the manufacturer intended to use 0x0
as the regulatory domain and that would ultimately yield
to US but since we cannot get confirmationf or this we
default this special case to one of our world regulatory
domains, specifically 0x64.

ath9k: Tune ANI function processing on AP mode during ANI reset

2009-07-21T16:07:43+00:00

For AP mode we must tune ANI specially for 2 GHz and
for 5 GHz. We mask in only the flags we want to toggle
on ath9k_hw_ani_control() through the ah->ani_function
bitmask, this will take care of ignoring changes during
ANI reset which we were disabling before.

ath5k: temporarily disable crypto for AP mode

2009-07-21T16:07:42+00:00

Pavel Roskin reported some issues with using AP mode without
nohwcrypt=1.  Most likely this is similar to the problem fixed
some time ago in ath9k by 3f53dd64f192450cb331c0fecfc26ca952fb242f,
"ath9k: Fix hw crypto configuration for TKIP in AP mode."

That only affects TKIP but it's easiest to just disable that and
WEP too until we get a proper fix in.

Atheros Kconfig needs to be dependent on WLAN_80211

2009-07-08T19:24:29+00:00

Atheros top level menu needs a "depends WLAN_80211" to properly indent
within menuconfig and xconfig interfaces.

This is purely a visual issue but it effects all subsequent drivers.
The issue is the top level menu does not include a dependency on
WLAN_80211 so within the tree structure, Atheros is at the same level as
WLAN_80211 but when WLAN_80211 collapsed, the menu disappears along with
all subsequent drives, so it is really a subordinate.

ath9k: Fix leak in tx descriptor

2009-07-07T16:55:26+00:00

When we reclaim the tx desc, we always assume that the
last desc is a holding desc, which is not true, and skip it.
If the tx queue is drained during channel change, internal
reset and etc, the last descriptor may not be the holding
descriptor and we fail to reclaim them. This results in the
following two issues.

1. Tx stuck - We drop all the frames coming from upper layer
due to shortage in tx desc.

2. Crash - If we fail to reclaim a tx descriptor, we miss to
update the tx BA window with the seq number of the frame
associated to that desc, which, at some point, result in
the following crash due to an assert failure in ath_tx_addto_baw().

This patch fixes these two issues.

ath5k: fix beacon_int handling

2009-06-19T15:50:23+00:00

(ath5k: remove conf->beacon_int usage)
removed bintval setting from ath5k_config. We need to init the
interval earlier and don't touch it in add_interface anymore.

Otherwise it will be set only once by upper layer through
bss_info_changed but not on second and further hostap executions.

We ended up having bintval 1000 which rendered the AP useless on
many clients.
