From b8dc6c5b0ed397b082334b98641debbbbec34e29 Mon Sep 17 00:00:00 2001 From: Serhey Popovych Date: Thu, 18 Jan 2018 16:04:35 +0200 Subject: [PATCH] vti6/tunnel: Unify and simplify link type help functions Both of these two changes are missing for link_vti6.c: commit 8b47135474cd ("ip: link: Unify link type help functions a bit") commit 561e650eff67 ("ip link: Shortify printing the usage of link type") Replay them on link_vti6.c to bring link type help functions inline with other tunneling code.
