[PATCH] brcmfmac: Turn off ARP offloading when configured for AP.

[PATCH] brcmfmac: Turn off ARP offloading when configured for AP.

[Arend van Spriel]

From: Hante Meuleman <meuleman@broadcom.com>

[backport of upstream commit b3657453f16a7b84eab9b93bb9a9a2901ffc70af]

ARP offloading should only be used in STA or P2P client mode. It
is currently configured once at init. When being configured for AP
ARP offloading should be turned off and when AP mode is left it can
be turned back on.

You didn't say which version(s) this is for, but it certainly doesn't
apply to 3.2.

I actually did the backport because I got notified the upstream commit 
did not apply to 3.9-stable (see [1]).

In 3.2 brcmfmac did not support AP mode so that explains the fact that 
is does not apply ;-)

Hi Greg,

I noticed your review announcement for v3.9.7 and did not see the change 
below. I sent it to stable because the original upstream commit did not 
apply. Did I miss some step in the process?

Arend

Ah, somehow I missed your patch, sorry about that, I do have it in my
mbox.  What kernel tree(s) do you want it to be applied to?  I'll pick
it up in my next round of releases.

thanks,

Thanks, Greg

I backported it for the 3.9 tree. It does not apply to 3.8 so I will 
have to create another backport if I need it there.

3.8 is long dead and not maintained by me anymore, but thanks.

Next time you submit stable patches, please let us know somewhere in the
patch/subject what tree it applies to, that makes our lives much easier,
otherwise I just guess and ususally get it wrong :)

thanks,

Hi Greg,

Forgot to ask, but it seems like Canonical is maintaining additional 
stable kernel branches. I guess I should contact them for those kernel 
versions (if I care), right?

They track Greg's stables to pick up the patches. Know from my own
experience, I didn't have to ping anyone :)

Yes, we're picking up cc: stable patches automatically when they apply
to the 3.8.y.z and 3.5.y.z "extended stable" branches[0], but we
certainly appreciate specific backports for those versions when they
don't apply cleanly.

Thanks, Kamal

I send a backport for 3.9 and tried it on 3.8, but it does not apply so 
I would have to backport it. I will have a look and find out where to 
send them. Probably that info is on the referred wiki.

Arend
