* [PATCH 5/7] rt2x00: wireless CLI ID and packet ID must not be 0
From: Ivo van Doorn @ 2009-08-17 16:55 UTC (permalink / raw)
To: John Linville; +Cc: linux-wireless, users, Benoit PAPILLAULT
In-Reply-To: <200908171854.50790.IvDoorn@gmail.com>
In the TX descriptor the Packet ID must not be 0,
so add 1 to the ID. The wireless CLI ID is not allowed
to be 0 either, but also must be initialized with the
wcid value rather then keyid.

In-Reply-To: <200908171855.40486.IvDoorn@gmail.com>
From: Benoit PAPILLAULT <benoit.papillault@free.fr>
rt2800pci can handle different retry rates,
it will always step 1 rate down after a failed
transmission so creating the retry rate list
for mac80211 is quite simple.

* [PATCH 1/7] rt2x00: Fix RFKILL polling
From: Ivo van Doorn @ 2009-08-17 16:53 UTC (permalink / raw)
To: John Linville; +Cc: linux-wireless, users
The rfkill_poll callback function in the drivers check a bit
to see if the RFKILL key has been pressed. However when the
bit is set it means the radio is active and the device can be
used.
The wiphy_rfkill_set_hw_state() function expects the inversed,
so '1' must be send when the radio must be disabled.

* [PATCH] wl1251: correct definitions for 0th bit defines
From: Bob Copeland @ 2009-08-17 15:18 UTC (permalink / raw)
To: linville, Kalle Valo; +Cc: linux-wireless
ACX_SLV_SOFT_RESET_BIT and ACX_REG_EEPROM_START_BIT are both defined
as "1" in the vendor driver code, but they were defined to be BIT(1)
("2") here.
The SOFT_RESET typo ensures that wl1251_boot_soft_reset() doesn't;
as a result the device hangs when trying to reprogram the PLL
registers while running.

Yeah, commit 6565a1c6d2e0754b5f1e8160252f6dc9493ed6c4 needs to be
backported. I suspect it applies as-is, John mind trying that? If not,
let me know and I'll port it.

Oh I should probably mention that
1) I only tested with hwsim, but
2) I don't think it will break much since it doesn't really change most
drivers.

BTW, at76c50x-usb is broken currently. The change of providing bssid to
the driver only after association broke it. I don't have time to fix it
right now, but I try to find some time next week.

This will make things a lot easier for wl1251 and wl1271. Thank you for
this.

* [PATCH] mac80211: remove deprecated API
From: Johannes Berg @ 2009-08-17 14:18 UTC (permalink / raw)
To: John Linville; +Cc: linux-wireless
All but two drivers have now stopped using the two
deprecated members radio_enabled and beacon_int,
so it's about time to remove them for good.

* [PATCH] mac80211: allow configure_filter callback to sleep
From: Johannes Berg @ 2009-08-17 14:16 UTC (permalink / raw)
To: John Linville; +Cc: linux-wireless
Over time, a whole bunch of drivers have come up
with their own scheme to delay the configure_filter
operation to a workqueue. To be able to simplify
things, allow configure_filter to sleep, and add
a new prepare_multicast callback that drivers that
need the multicast address list implement. This new
callback must be atomic, but most drivers either
don't care or just calculate a hash which can be
done atomically and then uploaded to the hardware
non-atomically.
A cursory look suggests that at76c50x-usb, ar9170,
mwl8k (which is actually very broken now), rt2x00,
wl1251, wl1271 and zd1211 should make use of this
new capability.

I don't know; rtl8192su & rtl8192e use a modified version of the
libipw stack, rather than the mac80211 stack found behind non-staging
drivers.

This is the correct fix for the threaded IRQ code. Apply this instead of the hack:

* [PATCH] iw: fix output qualifier for unsigned values
From: Arnd Hannemann @ 2009-08-17 10:46 UTC (permalink / raw)
To: linux-wireless@vger.kernel.org
[-- Attachment #1: Type: text/plain, Size: 353 bytes --]
Hi,
with 0.9.16 a "iw wlan0 station dump" gives the following output:
Station XX:XX:XX:XX:XX:XX (on wlan0)
inactive time: 4 ms
rx bytes: -1611945626
rx packets: 7643414
tx bytes: 1527923993
tx packets: 4829428
signal: -63 dBm
tx bitrate: 54.0 MBit/s
Seems to be the output qualifier %d is used wrongly in some cases.
This patch fixes that.
