For more sophisticated users, ability to manage networking is a key feature of LEDE/OpenWRT.

As configured by default, the ip OBJECTs of tunnel and neighbor are not included.

As noted in FS#1380 there is no straightforward way to "replace" busybox on a running system with a customized version.

Consider enabling these options by default

Looking at the size of the extracted busybox binary within the package (on the Ubuntu build machine) suggests this will add:

• 4096 bytes for ip_tunnel only
• 8192 bytes for both ip_tunnel and ip_neighbor
