direct the discovery protocol packets to physical functions, virtual functions, and ports associated with the discovery protocol packets based on the encoded extended discovery protocol information.
3. The information handling system of claim 1 , wherein a discovery protocol daemon executing on the management controller is configured to translate discovery protocol packet type-length-value information from an external port of the management controller to identifiers of virtual functions and physical functions of the host system.
4. The information handling system of claim 1 , wherein the management controller is further configured to, based on the extended discovery protocol information, discover virtual machines executing on the host system and associated with virtual functions of the network interface, wherein the network interface is single-root input/output virtualization enabled.

6. The information handling system of claim 1 , wherein the discovery protocol packets are encoded in accordance with one of Distributed Switch Architecture encoding, virtual local area network encoding, and Ethernet encoding.
7. A method comprising, in an information handling system comprising a host system including a host system processor and a network interface coupled to the host system processor and comprising a management controller communicatively coupled to the host system processor and configured to provide management of the information handling system:
capturing, by the network interface, discovery protocol packets having destinations associated therewith;
delaying forwarding of the captured discovery protocol packets to the respective destinations;
encoding, by the network interface, the discovery protocol packets with extended discovery protocol information comprising information regarding physical functions, virtual functions, and ports associated with the discovery protocol packets; and
subsequent to the encoding, forwarding the encoded discovery protocol packets to the respective destinations.
8. The method of claim 7 , further comprising:
receiving, by the management controller, discovery protocol packets with encoded extended discovery protocol information; and
directing, by the management controller, the discovery protocol packets to physical functions, virtual functions, and ports associated with the discovery protocol packets based on the encoded extended discovery protocol information.
9. The method of claim 7 , further comprising translating, by a discovery protocol daemon executing on the management controller, discovery protocol packet type-length-value information from an external port of the management controller to identifiers of virtual functions and physical functions of the host system.
10. The method of claim 7 , further comprising, based on the extended discovery protocol information, discovering virtual machines executing on the host system and associated with virtual functions of the network interface, wherein the network interface is single-root input/output virtualization enabled.
11. The method of claim 7 , wherein the discovery protocol comprises Link Layer Discovery Protocol.
12. The method of claim 7 , wherein the discovery protocol packets are encoded in accordance with one of Distributed Switch Architecture encoding, virtual local area network encoding, and Ethernet encoding.
13. An article of manufacture comprising:
a non-transitory computer-readable medium; and
computer-executable instructions carried on the computer-readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to, in an information handling system comprising a host system including a host system processor and a network interface coupled to the host system processor and comprising a management controller communicatively coupled to the host system processor and configured to provide management of the information handling system:
