Re: [ath9k-devel] modifying priority of UDP packets
I went through code in compat/net/mac80211, and seems I could not find code which does the the change in the Access Class of the frames (Apart from one function which is called for Linux v<2.6.27). I suppose the change directly happens in the driver then (I have to look through it though). IP QoS might be one thing that may help. This is layer 3 QoS, not sure what is layer 2 QoS done (I read these terms somewhere), but hopefully IP TOS field can be useful enough to change the priority of certain kind of UDP frame ? - Abhinav On Fri, May 24, 2013 at 2:43 AM, Holger Schurig wrote: > Have you tried the normal QoS stuff that IP supports?

Re: [ath9k-devel] modifying priority of UDP packets
Have you tried the normal QoS stuff that IP supports? The document http://www.tldp.org/HOWTO/Adv-Routing-HOWTO/ is antique by IT standards, but most (if not all) still holds true. Basically, you mark your important packets using firewall rules. Later those markings are used in the QoS part of the networking stack to prioritize those packets. A driver is the very wrong destination for such a solution: would you hack 1000 different ethernet-, WLAN- and Bluetooth drivers if you want to prioritize packets? Nope! ___ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
Re: [ath9k-devel] modifying priority of UDP packets
Well, I don't want to do it in the driver, if possible in mac80211 itself. I looked into net/mac80211/, but I did not find any specific hint where the TOS field is checked and subsequent allocation takes place. Any hint will be greatly appreciated ! - Abhinav On Thu, May 23, 2013 at 7:07 PM, abhinav narain wrote: > Hi all, > I wanted to modify the priority of one of specific UDP frames generated by > my specific application, > to be send on VI queue. > Can someone please tell, which files should I look into in compat-wireless > folder ? > - > Abhinav > ___ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
[ath9k-devel] modifying priority of UDP packets
Hi all, I wanted to modify the priority of one of specific UDP frames generated by my specific application, to be send on VI queue. Can someone please tell, which files should I look into in compat-wireless folder ? - Abhinav ___ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
