Abstract
A disclosed method may include (1) detecting, at a network stack of a network device, a packet that (A) is destined at least intermediately for a network interface of the network device and (B) has been flagged by the network stack to be dropped instead of forwarded to the network interface based on at least one characteristic of the packet, (2) instead of dropping the packet, forwarding the packet to an alternative network interface of the network device that analyzes content of packets, (3) identifying, at the alternative network interface, the characteristic of the packet, and then (4) executing, based on the characteristic of the packet, at least one action in connection with the packet that improves the performance of the network device. Various other apparatuses, systems, and methods are also disclosed.
