From 2601e4ed3f643da2cd4e55f174355e02c0636a04 Mon Sep 17 00:00:00 2001 From: Eugene Crosser Date: Thu, 16 Jun 2016 16:18:56 +0200 Subject: [PATCH] qeth: enable scatter/gather by default Set scatter/gather ON by default on OSA, for both layer 2 and layer 3 modes. We always use fragmentation over QDIO anyway, so let the upper layers of the stack take advantage of that.
