From fbc2ac336796ea686211ca411b23cb0527fca57d Mon Sep 17 00:00:00 2001 From: Ron Mercer Date: Mon, 5 Jul 2010 12:19:41 +0000 Subject: [PATCH] qlge: Make adapter drop frame errors and pass up csum errors. Statistics are available and the driver doesn't need the actual frame. This TCP/UDP and IP headers checksum errors will still be passed to the driver.
