I am no expert on FreeBSD internals. I was wondering about this exact aspect and was hoping to get feedback just like this. > Why do you want to replicate this at NETGRAPH level? > ng_iface(4) was created to be generic network interface to NOT duplicate such > things. > After reading this, I went back and read the manual to ifconfig again. My wish is based on a misconception. I thought that the point-to-point vs. broadcast setting was general for all interfaces and could be readily set by using ifconfig ptp. As there was already duplication on that setting, I didn't see any real issue with setting the MTU via netgraph as well. Realising this is not the case has made me see that my idea isn't a great one. At least I know how to submit a patch in the future if I get actually well thought out ideas.
