Description

TXfeedback doesn't work on newer Versions of madwifi. I use Click (read.cs.ucla.edu/click/) to build software routers. I use a wifi-card with Atheros 5212 chipset. My kernel is a 2.6.19.2 from pyramid.metrix.net. With the madwifi-driver-version 0.9.1 (svn.madwifi.org/madwifi/tags/release-0.9.1) the txfeedback works great. i got back every frame which i sent with some statistic (number of retries,...). But with newer version it doesn't work. (revision 2721 is the smallest which i was able to check out from svn.madwifi.org/madwifi/trunk). Since Monitor mode packet injection broken starting in svn r3500 (see Ticket 1927), i didn't try versions greater than 3500, because i need raw packet injection to work with click. For debugging, mybe it will be helpful to check older version than 2721. How can i get access to those older versoin ? maybe than i'm able to find the first not working version and to find the changes which makes the txfeedback unusable.

Best regards Robert
