Thanks to those who pointed me in the right direction, here is a patch to the e100 (2.4.23-pre9) that allows it to capture all frames, bogons included. It also coppies the FCS to the skb so ethereal et al can read it. It utilizes ethtool commands to get/set the rx-all feature, and uses a new flag in the skbuff (and socket struct) structure to determine when to disable generating the FCS on transmit. I have the entire patch that adds the management bits and flags, but as usual, it's mixed in with various other things... I've done some initial testing and it seems to work as planned... If this patch or some version thereof has a possibility of being accepted, I'll be happy to break out the other bits into a clean patch for a more thorough review. If this is DOA, then I thank you for your time anyway! Jeff, Dave, et al, please let me know if this is of interest! Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
