This PR fixes an issue where echo replies were being sent through the same interface the matching echo request was received. That results in dropped replies in cases a router is connected to more than one viable next-hop.

Example:

example with fix

Without the fix, the response shown on the example was being sent to device 2 with the MAC address of device 3.
