From 70a615d7daa04923d9f255307de26819f2f6dbd4 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Tue, 24 Apr 2018 14:33:37 +0800 Subject: [PATCH] team: fix netconsole setup over team MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit [ Upstream commit 9cf2f437ca5b39828984064fad213e68fc17ef11 ] The same fix in Commit dbe173079ab5 ("bridge: fix netconsole setup over bridge") is also needed for team driver. While at it, remove the unnecessary parameter *team from team_port_enable_netpoll(). v1->v2: - fix it in a better way, as does bridge.
