Subject: [iproute2-next] tipc: support 128bit node identity for peer removing
From: Hoang Le <hoang.h.le@...tech.com.au>
Problem:
In kernel upstream, we add the support to set node identity with
128bit. However, we are still using legacy format in command tipc
peer removing. Then, we got a problem when trying to remove
offline node i.e:
$ tipc node list
Node Identity Hash State
d6babc1c1c6d 1cbcd7ca down
$ tipc peer remove address d6babc1c1c6d
invalid network address, syntax: Z.C.N
error: No such device or address
Solution:
We add the support to remove a specific node down with 128bit
node identifier, as an alternative to legacy 32-bit node address.
