Subject: netxen: do_rom_fast_write error handling

Compiler warning spots real error!

The function do_rom_fast_read called in do_rom_fast_write can fail
and leave data1 unset. This causes a compile warning.
The correct thing is to propagate the error out.

From 3176ff3ee71bddbd1d68e6a9e28dbcf0a2960c95 Mon Sep 17 00:00:00 2001

Subject: NetXen: Use multiple PCI functions

NetXen: Make driver use multiple PCI functions.
This patch will make NetXen driver work with multiple PCI functions. This will
make the usage of memory resources as well as interrupts more independent
among different functions which results in better throughput. This change has
been done after the multiport support is added in firmware.

From 13ba9c7714cfa40821d29090442de14d01d6eb33 Mon Sep 17 00:00:00 2001
From: Mithlesh Thukral <mithlesh@netxen.com>
Date: Fri, 20 Apr 2007 07:53:05 -0700
Subject: NetXen: Removal of redundant argument passing

NetXen: Removal of redundant function call parameters and bug fixes.
This patch will remove the redundant paramters which were being passed to
many functions since now adapter->portnum can be used.

From: Mithlesh Thukral <mithlesh@netxen.com>
Date: Fri, 20 Apr 2007 07:53:52 -0700
Subject: NetXen: Multi PCI support for Quad cards

NetXen: Fix the multi PCI function for cards with more than 2 ports.
This patch fixes the working of multi PCI capable driver on cards with
more than 2 ports by adding the addresses for their rings and sizes.

From: Mithlesh Thukral <mithlesh@netxen.com>
Date: Fri, 20 Apr 2007 07:55:26 -0700
Subject: NetXen: Port swap feature for multi port cards

NetXen: Port Swap feature
This patch will allow a port numbers on the card to be swapped in
host driver. This feature is applicable to cards having more than
1 port.
