Independent network interfaces for virtual network environments

A computer program product for providing a network independent interface, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• use, by the processor, a bridge device as a root interface for supporting a kernel bridge infrastructure;
• add, by the processor, a plurality of virtual network interface cards (vNICs) as bridge ports;
• and
• modify, by the processor, behavior of the kernel bridge infrastructure using netfilter hooks, the modified behavior including prevention of forwarding of broadcast packets between bridge ports and setting a source media access control (MAC) address of an egress packet to a corresponding MAC address of a vNIC, resulting in a network independent vNIC,
• wherein the bridge device learns the MAC address on each bridge port and selects a vNIC for egress packets.
