[ath5k-devel] Disable MAC layer ack
Hi, I am interested in disabling the MAC layer ack. I have read http://www.mail-archive.com/ath5k-devel@lists.ath5k.org/msg04587.html Is there any chance of a hook being put into ath5k so that it could be enabled or disabled with an iwpriv or something similar. It seems like it is part of the 802.11e framework http://en.wikipedia.org/wiki/IEEE_802.11e-2005#NoAck It would also be useful for anyone doing long distance networking or experimenting with TDMA based MAC layers. Thanks for your time, Dave ___ ath5k-devel mailing list ath5k-devel@lists.ath5k.org https://lists.ath5k.org/mailman/listinfo/ath5k-devel
Re: [ath5k-devel] Disable MAC layer ack
If it's anything like what ath9k does, there's a flag that the upper layers can set which marks that particular frame as not requiring an ACK. So you wouldn't require it to be done via an iw command - you'd just appropriately tag your data frames.

Re: [ath5k-devel] Disable MAC layer ack
There's a bit in the TX descriptor which should be labelled something like noack / NOACK. Just start there and work your way up. :) Sorry, I'm knee deep in radar pattern matching code at the moment...

Adrian, do you have any information or links that might explain how the higher layers set the QoS flags of NoAck in 802.11? I would happily buy ath9k compatible devices if I thought this would be possible. Thanks Dave On 20/01/12 05:59, Luis R.
