[ath9k-devel] Extra redundancy in certain frames.

[abhinav narain]

Hi Folks,
I wanted to have some extra redundancy to be present in certain
packets, like DNS frames so that I can increase the probability
of it getting across.

I was interested in knowing how can I achieve this in ath9k.
Which functions should I look into ?
Do I have to parse the frame in driver before transmitting to
find out it is a DNS packet or is there something else that can
be done cleverly ?

PS: I understand that the sender and the receiver both have
to be modified for such an aim.

Thanks,
Abhinav

I'd first make sure they are sent on the VO (high priority)
queue.  That could be done in the stack, or could be done in
the dns process for the station.  For AP, it would probably have to
be done in the stack.

Thanks,
Ben

Yeah, I'd dump them into the VO queue and set their retry counts much higher.

[ath9k-devel] Extra redundancy in certain frames.

[abhinav narain]

Yeah, that was my first guess-- to use a different access class than BE!
I want to do add some extra redundancy bits in the payload .. I wasn't sure
if it's easier to
do it in mac80211 susbsystem or in the driver .. I see one cannot know
anything about
in the packet in the driver as they are just linked list, but I wasn't sure
where to do in mac80211.

Thanks,
Abhinav

It sounds like there needs to be an optional TX field which says "ok,
now really, how many retransmits?"
