The arp command is part of userland, not the kernel. It is a utility which runs from user-space and can be run from any running system. Unless your file system is embedded in your kernel, you shouldn't need to rebuild your kernel. For arp, since it is in /usr/sbin, the source is in src/usr.sbin/arp. The file arp.c is the one you want to edit. So check our that directory, or go to it in your existing checkout, and edit arp.c. Run "make" to rebuild the arp binary. If you want to install it on your running system, do "make install" — you have to do that as root, so use sudo or su first. You may want to send your changes to the list after you make them, as although this is a very simple change, it may be something the wider developer community would be interested, and could conceivably be committed. For example, if you added a new command line option to hide expiration times, or to make the output more machine-readable, or something of that sort, that might be of general utility. Good luck!
