From 1fbe63235893e5dce28fe91d8465dd231b0cb3d9 Mon Sep 17 00:00:00 2001
From: Dhananjay Phadke <dhananjay@netxen.com>
Date: Tue, 7 Apr 2009 22:50:44 +0000
Subject: netxen: annotate register access functions

o remove unnecessary length parameter since register access
  width is fixed 4 byte.
o remove superfluous pci_read_normalize and pci_write_normalize
  functions.

From f98a9f693b5f4919d9c4085a2fd8d67c7e152f3e Mon Sep 17 00:00:00 2001
From: Dhananjay Phadke <dhananjay@netxen.com>
Date: Tue, 7 Apr 2009 22:50:45 +0000
Subject: netxen: sanitize function names

Replace superfluous wrapper functions with two macros:

NXWR32 replaces netxen_nic_reg_write, netxen_nic_write_w0,
netxen_nic_read_w1, netxen_crb_writelit_adapter.

NXRD32 replaces netxen_nic_reg_read, netxen_nic_read_w0,
netxen_nic_read_w1.

From f7185c71234434d48b96f9a0387737df1759a4af Mon Sep 17 00:00:00 2001
From: Dhananjay Phadke <dhananjay@netxen.com>
Date: Tue, 28 Apr 2009 15:29:11 +0000
Subject: netxen: fix firmware download

o hold the firmware in memory across suspend, since filesystem
  may not be up after resuming.
o reset the chip after requesting firmware, to minimize downtime
  for NC-SI.

Subject: netxen: fix irq tear down and msix leak.

o Fix the order of irq and hardware context teardown.
  Also synchronize the interrupt in dev close() before
  releasing tx buffers.

o Fix possible msi-x vector leak if available vectors are
  less than requested.

o Request multiple msix vectors only if hardware supports
  multiple rx queues.

This board doesn't suppot msi-x well due to msi-x table
mapping (hardware) issue.

Subject: netxen: fix msi irq setup

The pdev->irq was not saved in netxen_adapter, causing request_irq()
with invalid irq number.

This was broken in commit be339aee634d5cb98a8df8d6febe04002ec497f3
("netxen: fix irq tear down and msix leak.").

Subject: net: dont update dev->trans_start in 10GB drivers

Followup of commits 9d21493b4beb8f918ba248032fefa393074a5e2b
and 08baf561083bc27a953aa087dd8a664bb2b88e8e
(net: tx scalability works : trans_start)
(net: txq_trans_update() helper)

Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Multi queue drivers can
avoid one cache miss (on dev->trans_start) in their start_xmit()
handler.

Exceptions are NETIF_F_LLTX drivers (vxge & tehuti)
