Lets go with this approach for now, and if it bites us in the ass we
now not to do that again :)
BTW Thanks so much for all these patches, I'm merging them now, I
counted 6, 3 for compat, 3 for compat-wireless, if I missed anything
please let me know. Going to force out a new tarball now.
compat:
compat: backport convert multicast list to list_head.
compat: Add linux/version.h include before using it.
compat: Add definitions needed for libertas sdio driver.
compat-wireless:
compat-wireless: include net and trace includes form compat
compat-wireless: Remove use of sdio quirks attribute
compat-wireless: backport convert multicast list to list_head.

I think the idea from the original announcement is for each pair of
organizations with duplicate applications, to contact each other, for
one of the organization to drop the student's application so the other
one can proceed. e.g. if a student applies to both linux foundation
and gnome (for example), the linux foundation admin should contact the
gnome admin to decide which organization to take the student (and
which one to withdraw. As for the question itself, somewhere under:

+Backport commit 22bedad3ce112d5ca1eaf043d4990fa2ed698c87:
+ net: convert multicast list to list_head
+
+ Converts the list and the core manipulating with it to be the same as uc_list.
+
+ +uses two functions for adding/removing mc address (normal and "global"
+ variant) instead of a function parameter.
+ +removes dev_mcast.c completely.
+ +exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for
+ manipulation with lists on a sandbox (used in bonding and 80211 drivers)
+
+This also backport commit 2f787b0b76bf5de2eaa3ca3a29d89123ae03c856

* Google Summer of Code 2010 - Please resolve duplicates

Hi,
two students who applied for your projects have applied also for another
organization's project and they got accepted by us and by the other
organization.
Until Wednesday Google wants these situation to be resolved until
Wednesday April 21, 17:00 UTC. Please contact the students and/or the
organization to agree on one of the project for each student.
In addition, the ranking of the students (to decide who actually gets
our slots) and the mentor assignments have to be finalized by the same
date and time.
Duplicates not be resolved until then will be resolved on an IRC meeting
on Wednesday April 21 at 19:00 UTC. The meeting takes place in the #gsoc
channel on Freenode.
Please mail me if a mentor needs to be (re)assigned.
Till
----------------------------------------------------------------------
Hi all,
I have opened the duplicate information for students to all of your
orgs. If you view your student proposals now the ones that are ranked
to be accepted that are duplicated with another org will be marked in
red. If you click on the proposal you will see the contact information
for the other organization(s)'s admins near the bottom of the
proposal.
You must also have a mentor assigned to all the students in your top N
slots by now. If you do not have a mentor assigned to them the
duplicate detection script will not pick them up and we may have
duplicates we don't know about. That is bad, please fix that if its
the case.
Please try to resolve as many of these duplicate situations via email
in the next two days as possible - contact your fellow organizations,
be clear with each other about who is taking the student, and then
rank the student up if you are accepting him/her or mark the student
ineligible with a public comment that you have marked it ineligible
because of a duplicate situation if you are not taking the student.
The deadline for changing rankings is 17:00UTC on Wednesday, April 21.
All duplicates that have not been resolved by 17:00 UTC will be taken
to the IRC meeting at 19:00 UTC.
Cheers,
Carol

I don't have any names for that. It's stuff from a debugging register -
adapted from Atheros code...

Where did you get all that magic? If it's from Atheros documentation,
maybe you could give those numbers descriptive names?

This will be possible, but as I see, only in some easy parts where the
patch looks like the quote above.
I will change that and resend this patch.

I think the if defs are better than a conditional define in every file
that needs it. It will result in strange compile errors if someone uses
addr for an other addresses.

This change depends on some changes structs in

Yes that could be done, but I think it is much more clear to use this
patch here, because we do not need __hw_addr_init, because
local->mc_list is of a completely different type.

No idea. I've never used fixed-rate. I guess it could, if it uses 11M
for communicating with a peer that it for some reason did not enable
this rate for.

In-Reply-To: <1271699857-12366-3-git-send-email-nbd@openwrt.org>
Include MCS0-31 and also add SGI for HT20. This makes it
possible to support more different rate combinations with
newer hardware.
Based on a patch by Selvam. T.

it single-stream only and multiply the values by the numer of streams.

If you still have this setup available, could you please try out the
recent patch "mac80211: pass HT changes to driver when off
channel" (http://thread.gmane.org/gmane.linux.kernel.wireless.general/49855 ) ?
Thank you
