From 541ae68f6ddf1c27aa6879935ce541f110484202 Mon Sep 17 00:00:00 2001 From: "raghavendra.koushik@neterion.com" Date: Wed, 3 Aug 2005 12:36:55 -0700 Subject: [PATCH] [PATCH] S2io: Support for Xframe II NIC Hi, This patch provides basic support for the Xframe II adapter. Includes the following changes: 1. New values to program XAUI interface. 2. Print the PCI/PCI-X mode(bus frequency, width). 3. Remove EOI from reset during intialization. 4. Enable all 8 PCCs if Xframe II adapter. 5. Programs the RLDRAM size depending on the device. (Note: RLDRAM size on XFARME-I is 64Mb whereas on XFRAME-II it's 32 Mb). 6. Enable extended(64-bit) statistics counters. 7. Program timer interrupt duration based on PCI/PCI-X clock speed. 8. Not required to save/restore PCI config space before/after reset.
