From 0d979f74a920bcc18eb451d363f02083a625294c Mon Sep 17 00:00:00 2001 From: Ron Mercer Date: Thu, 12 Feb 2009 16:38:03 -0800 Subject: [PATCH] qlge: bugfix: Fix TSO breakage. Moved the buffer mapping to a point after TSO logic has modified the iph->check field. We were seeing stale data on the PCIe bus. Signed-off-by: Ron Mercer Signed-off-by: David S.
