Hmm.. I think I need to see the patch for doing this before being able to decide whether I'd like this or not.. Michael MIC is a bit unfortunate design since it happens at MSDU, not MPDU level. Because of this, most hardware designs have to do something special when fragmentation is used. If the fragmentation is done in the stack, it may be difficult to move the Michael MIC operations into the driver since they need to happen before fragmentation (which would be done in the stack in this case).. Other than this special case, it sounds reasonable to keep most of the small hardware design changes hidden in the driver code as long as the functions that are exported from the stack are the same ones that the stack would be using anyway (i.e., not having to maintain two versions of the same code). -- Jouni Malinen PGP id EFC895FA - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
