Can you elaborate on what happens? I was under the impression that the firmware would handle TSF stuff. Also the "IBSS leader" is a new thing to me. I remember from the specs that the device should accept the TSF from _any_ beacon. Not just a "leader". Am I mislead? :) I also fail to see how we could _ever_ set the TSF to something remotely correct from the driver because of the FIFO delay. > > > Assaf Krauss (1): > > iwlwifi: W/A for the TSF correction in IBSS I cannot find this patch in wireless-testing and I don't have a copy of wireless-2.6 here. Can you send me the patch, or explain what it does? -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
