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 - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
