1. A method for debugging network connections, comprising:
- receiving a packet for a first destination by a network interface card (NIC);
classifying the packet;
sending the packet to a first receive ring associated with the NIC; and
sending the packet from the first receive ring to a first virtual NIC,wherein the first virtual NIC is associated with a second destination, andwherein the second destination is used to debug the first destination.
