Zeeb from comment #4) > What's the reason the change doesn't get merged to stable/15? > Given it's an extension to the struct it looks like it is totally fine. While the given change indeed is the change that supposedly fixed the probl= em and it indeed seems mergeable, the change heavily depends on earlier change= s, where a hardcoded 4.3BSD protocol attach to ifnet was refactored to EVENTHANDLER(9). And that is a much more intrusive change. Potentially, the epoch delayed free of protocol softc hanging off ifnet may= be crafted on top of stable/15, without preceeding refactorings. But that won'= t be a merge of a well tested change. That would be a new, specific to stable/15 code. I'd rather not go this way until somebody does a very extensive testi= ng of it. --=20 You are receiving this mail because: You are the assignee for the bug.=
