From 239ff408ddd8fa7a19c53ed247daec855ff11ea2 Mon Sep 17 00:00:00 2001 From: Ursula Braun Date: Fri, 18 Sep 2015 16:06:50 +0200 Subject: [PATCH] qeth: move OSA portname into deprecated status An OSA-Express port name was required to identify a shared OSA port. All operating system instances that shared the port had to use the same port name. This requirement no longer applies. Signed-off-by: Ursula Braun Signed-off-by: David S.
