Ben Greear wrote: The dev_queue_xmit method is fairly well documented in dev.c, but there are zero comments in the netdevice.h file to explain what the acceptable return values for hard_start_xmit are. Actually, looks like I'm wrong here. The comments in dev.c say that error codes are < 0, but in fact, this can easily return NET_XMIT_DROP which is a positive value (1). Maybe the truth is that any non-zero return value from dev_queue_xmit is an error? Ben -- Ben Greear <greearb@xxxxxxxxxxxxxxx> Candela Technologies Inc http://www.candelatech.com |
