The outgoing packets are dropped in the enqueue routine of the queing
discipline
if there is not enough space in the queue.
dev_queue_xmit calls q->enqueue which resolves to pfifo_fast_enqueue() when
the
default queuing discipline is used. You can see the packet drop in this
routine.

Subject: outbound queue overflow
I wonder where in the Linux networking code, we can see if outgoing
packets are
dropped due to lack of buffer space (full queue). In particular,
IP->ETH.
I looked e.g. at dev_queue_xmit in net/core/dev.c
but could not find out if this is the right place to look at.
Hope anybody can give me a helping hint
Cheers,
Thiemo
