+From: Marek Behún <marek.be...@nic.cz>
+Subject: [PATCH RFC iproute2-next] iplink: allow to change iplink value
+Date: Sat, 24 Aug 2019 04:42:51 +0200
+
+Allow to change the interface to which a given interface is linked to.
+This is useful in the case of multi-CPU port DSA, for changing the CPU
+port of a given user port.
