netstat can show the number of frames received/sent (Ipkts/Opkts), received/sent with error (Ierrs/Oerrs), etc. But you may get more detailed stats with kstat.
If interface is e1000g0, try "kstat -m e1000g -i 0". Similarly for Realtek interface you can get its statistics using kstat. To understand what each entry in kstat is for, you can go through the driver source.

The network protocol is UDP, and my machine has a realtek driver. Is there a way to pin point the number of packets lost at the NIC, and how many in the kernel. I need to do it for another machine which has the e1000g driver for the NIC. Is netstat able to capture this, or dtrace? Thank you, Vish
