Subject: qlcnic: Use pci_enable_msix_exact() instead of pci_enable_msix()

As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range()  or pci_enable_msi_exact()
and pci_enable_msix_range() or pci_enable_msix_exact()
interfaces.

Subject: qlcnic: Optimize MAC learning code

* Use rx_mac_learn instead of mac_learn and eSwitch flag check in Rx path of
  82xx adapter.
* Check for MAC filter overrun only after driver scans through cached MAC address list.
  This will help to update the time stamp of cached MAC addresses even if
  adapter runs out of MAC address filter limit.
* Remove expensive log thrown by driver when MAC address filters are exhausted

o SR-IOV VF can be uplinked to bridge/macvtap device with this change.
o Refactor SR-IOV enable/disable code. We cannot take rtnl lock
  while enabling/disabling SR-IOV as VF probe will take an rtnl
  lock.
o Disable spoofchk by default.

Subject: qlcnic: Add support to process commands in atomic context

o Commands from VF may sleep during PF-VF communication.
  Earlier we use to process qlcnic_sriov_vf_set_multi
  function in process context. Now individual commands
  that are called in atomic context are processed in
  process context without waiting for completion of
  command.

From d747c3337484afac9953c44ea56a912869778559 Mon Sep 17 00:00:00 2001
From: Rajesh Borundia <rajesh.borundia@qlogic.com>
Date: Fri, 9 May 2014 02:51:31 -0400
Subject: qlcnic: Add mac learning support to SR-IOV VF.

o SR-IOV VF can be uplinked to bridge/macvtap device.
  Enable mac learning to support communication through
  embedded switch.
o Learn vlan filters based on QLCNIC_VLAN_FILTERING flag.

Subject: qlcnic: Collect firmware dump using DMA on 82xx adapters

o Add support to collect RDMEM section of firmware dump
  using PEX DMA method.
o This patch uses most of the code used for PEX DMA support
  on 83xx series adapters and some refactoring.

Subject: vlan: rename __vlan_find_dev_deep() to __vlan_find_dev_deep_rcu()

The __vlan_find_dev_deep should always called in RCU, according
David's suggestion, rename to __vlan_find_dev_deep_rcu looks more
reasonable.

net: get rid of SET_ETHTOOL_OPS

Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone.
This does that.

Mostly done via coccinelle script:
@@
struct ethtool_ops *ops;
struct net_device *dev;
@@
-       SET_ETHTOOL_OPS(dev, ops);
+       dev->ethtool_ops = ops;

Compile tested only, but I'd seriously wonder if this broke anything.

Subject: net-next:v4: Add support to configure SR-IOV VF minimum and maximum
 Tx rate through ip tool.

o min_tx_rate puts lower limit on the VF bandwidth. VF is guaranteed
  to have a bandwidth of at least this value.
  max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth
  of up to this value.

o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced
  which takes 4 arguments:
  netdev, VF number, min_tx_rate, max_tx_rate

o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler.

o Drivers that currently implement ndo_set_vf_tx_rate should now call
  ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth
  greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet
  implemented by driver.

o If user enters only one of either min_tx_rate or max_tx_rate, then,
  userland should read back the other value from driver and set both
  for IFLA_VF_RATE.
  Drivers that have not yet implemented IFLA_VF_RATE should always
  return min_tx_rate as 0 when read from ip tool.

o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then
  IFLA_VF_RATE should override.

o Idea is to have consistent display of rate values to user.

o Usage example: -

  ./ip link set p4p1 vf 0 rate 900

  ./ip link show p4p1

Subject: qlcnic: Pre-allocate DMA buffer used for minidump collection

Pre-allocate the physically contiguous DMA buffer used for
minidump collection at driver load time, rather than at
run time, to minimize allocation failures. Driver will allocate
the buffer at load time if PEX DMA support capability is indicated
by the adapter.
