The NKE docs, in the section "Network Interfaces and Protocol
Plumbers" states the following note:
"Since more than one developer might attempt to register plumbers for
a given interface type, your KEXT should be prepared to handle such a
situation. If the demux descriptors are standard, it should be
possible for your KEXT to work with a third-party plumber."
Can someone expand on this for me to shed light on what "working" with
third party plumbers actually means? Specifically, is it possible to
have multiple plumbers for a specific interface type and if so, how is
this supposed to work?
I have run into a problem with calling proto_plumb_handler() for
IFNET_FAMILY_TUN, when an existing TUN NKE already exists.
