From b75cc0e4c1caac63941d96a73b2214e8007b934b Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Wed, 24 Nov 2010 08:31:46 +0000 Subject: tg3: Assign correct tx margin for 5719 Commit d309a46e42542223946d3a9e4e239fdc945cb53e, entitled "tg3: 5719: Prevent tx data corruption", was supposed to contain the tx margin adjustment but it looks like it somehow was omitted. This patch fixes the problem. Signed-off-by: Matt Carlson Reviewed-by: Michael Chan Signed-off-by: David S.
