* [PATCH 13/22] brcm80211: use endian annotation for scan time configuration
From: Arend van Spriel @ 2011-10-12 18:51 UTC (permalink / raw)
To: linville; +Cc: linux-wireless, Arend van Spriel
In-Reply-To: <1318445492-24207-1-git-send-email-arend@broadcom.com>
For scanning several timeout parameters are configured on the device.
These parameters have been endian annotated and converted appropriately.

The scan related functions provide scan parameters to the device
which need to be in little-endian. These parameters have been
annotated and conversions were placed as needed.

- removed unneeded fn prototypes from include files.
- explicitly marked fn prototypes as extern in include files.
- reordered functions to account for removed forward declarations
in include files.
- removed unused functions: brcms_c_txflowcontrol_override,
brcms_c_txflowcontrol_prio_isset, brcms_c_txflowcontrol.

* [PATCH 05/22] brcm80211: fix sparse endianess error in mac80211_if.c

The ht capabilities provided upon registration with mac80211 must
be in little endian. This was fixed adding cpu_to_le16() conversion.

* wl12xx.git is back on git.kernel.org
From: Luciano Coelho @ 2011-10-12 18:46 UTC (permalink / raw)
To: linux-wireless
Hi,
Now that git.kernel.org is working again and I got my account back, the
official wl12xx.git tree is back to it's original place:
git://git.kernel.org/pub/scm/linux/kernel/git/luca/wl12xx.git
And the usual branches are back, master (used for development) and
wl12xx-next (used by me for integration). All wl12xx tags were also
pushed back to to repository.
I'll keep updating the wl12xx.git repo in github for a while, but I
don't know for how long, so I don't recommend using it anymore.

The above hunk doesn't apply, because I have this:
rx_status->rate_idx = rtlwifi_rate_mapping(hw,
(bool)GET_RX_STATUS_DESC_RX_HT(pdesc),
(u8)GET_RX_STATUS_DESC_RX_MCS(pdesc),

Do you perhaps have another patch applied which you haven't sent?

For the record, I said this to you on IRC but you weren't around I
guess. This patch (with the other ones) is now passing a bogus sdata/vif
pointer to drivers -- e.g. for monitor mode interfaces from
ieee80211_do_open -> ieee80211_set_wmm_default -> drv_conf_tx.
I suspect the way to fix this would be to move the call to
ieee80211_set_wmm_default into the last switch statement in do_open,
could you please look into it?

Larry, just a little more info on this issue, FYI.
It would seem the problem is certainly specific to the 'Inventra' mUSB
host found in recent TI ARM products and ADI Blackfin devices.
I have added a PCI express NEC USB 2.0 host controller card to my ARM
Cortex A8 system, and the r8712u devices work just fine when connected
via that host controller. (Albeit only at 20MBps rate, but that's
because the host controller is rather poor in general).
We have now raised this problem with TI USB experts.

So I'm taking it that the driver is now in the wireless-next tree?
That's great, I'll queue the patch up later today.
And thanks so much for working with us, I know it can be hard at times,
but I hope you will agree that the end result is much better than what
we started out with.

* [PATCH] staging: brcm80211: remove brcm80211 driver from the staging tree

Hi Greg,
John recommended to do the delete through your staging tree. Thanks for
the ride. It has been a learning experience for all of us here. Apart
from the significant cleanup (which needs ongoing work for sure) it took
some time to find the right way of working in coordinating our changes
with community patches.
The removal patch was just as big as the mainline patch so it has been
uploaded to linuxwireless.org:

Regards,
