From 5fbd7e24da874a1c7b06ae6b10bbf2d71c1b6a11 Mon Sep 17 00:00:00 2001 From: Matheos Worku Date: Thu, 28 Feb 2008 21:25:43 -0800 Subject: [PATCH] [NIU]: Add Support for Sun ATCA Blade Server. Ports 0 and 1 of the NIU device are connected to extended fabric through SERDES. Ports 2 and 3 are connected using RGMII Fiber mode.
