From d3fd38637febad007bcc692bd79d5af08a17689d Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Sat, 6 Jan 2018 17:30:38 +0100 Subject: lantiq: create ATM/PTM interfaces with dsl as netdev name Renaming an atm etherbride using 'ip link' (via hotplug) is racy since the original netdev might disappear before br2684ctl has finished appling it's setting: local2.notice br2684ctl[1667]: Interface "nas0" created sucessfully local2.notice br2684ctl[1667]: Communicating over ATM 0.8.35, encapsulation: LLC kern.info kernel: dsl0: renamed from nas0 kern.err kernel: br2684:br2684_regvcc: tried to attach to non-existent device local2.err br2684ctl[1667]: Could not configure interface:No such device or address By passing the final used netdev name to br2684ctl_wrap another race condition workaround will be enabled again. Change the lantiq ptm driver to create a netdev with the name dsl as well. Albeit the rename via 'ip link' works fine so far, using a different approach for ptm then atm could be confusing.
