Subject: Re: [PATCH] mctp: Remove only static neighbour on RTM_DELNEIGH

That's correct. There may be a future facility for the kernel to perform
neighbour discovery itself (somewhat analogous to ARP), but only the
static entries are possible at the moment.

Yes, it'll be a no-op now; I'm not aware of any changes coming that
require parameterisation of the neighbour type yet.

Gagan - can you provide any context on this change?

Cheers,


Jeremy
