Hi, does somebody know, which is the default queue where outgoing packets are getting queued by the kernel? I don't wanna use any traffic shaping. Just need to monitor that queue/buffer for each device/interface to count some kind of packetloss, so i can see very fast when the buffer is full and no packets can leave the device. i read about queuing disciplines, but it didnt really helped me. It seems to me that the default queue is a plain fifo.and i see the enqueue call (in dev_queue_xmit(struct sk_buff *skb)) of net/core/dev.c. but i have difficulties to find the way an IP packet goes after that.
