From 764895d3039e903dac3a70f219949efe43d036a0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Stefan=20Br=C3=BCns?= Date: Wed, 8 Feb 2017 02:46:33 +0100 Subject: [PATCH] sierra_net: Skip validating irrelevant fields for IDLE LSIs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When the context is deactivated, the link_type is set to 0xff, which triggers a warning message, and results in a wrong link status, as the LSI is ignored.
