13800469d4 igb: Add Anti-spoofing feature support
Add support for the anti-spoofing feature in the HW.  Packets from
VF devices with spoofed MAC addresses or VLAN tags will be blocked
and an event generated.  When the watchdog task runs it will call a
function to check if any spoof events occurred.  If an event was
detected then a warning message is dumped to the system log.

Gasparakis, Joseph
1b5dda331f igb: Some fine tuning
This patch does the following:

1. Changes the existing supported device id's so now DH89xxCC is not supported when EEPROM is not read.
2. Adds two more device ids for DH89xxCC in backplane mode and SFP.
3. Driver now initializes previously possibly uninitialized value in igb_reset_mdicnfg_82580().

eab6d18d20 vlan: Don't check for vlan group before vlan_tx_tag_present.
Many (but not all) drivers check to see whether there is a vlan
group configured before using a tag stored in the skb.  There's
not much point in this check since it just throws away data that
should only be present in the expected circumstances.  However,
it will soon be legal and expected to get a vlan tag when no
vlan group is configured, so remove this check from all drivers
to avoid dropping the tags.

12dcd86b75 igb: fix stats handling
There are currently some problems with igb.

- On 32bit arches, maintaining 64bit counters without proper
synchronization between writers and readers.

- Stats updated every two seconds, as reported by Jesper.
   (Jesper provided a patch for this)

- Potential problem between worker thread and ethtool -S

This patch uses u64_stats_sync, and convert everything to be 64bit safe,
SMP safe, even on 32bit arches. It integrates Jesper idea of providing
accurate stats at the time user reads them.

2d0bb1c1f4 e100/e1000*/igb*/ixgb*: Add missing read memory barrier
Based on patches from Sonny Rao and Milton Miller...

Combined the patches to fix up clean_tx_irq and clean_rx_irq.

The PowerPC architecture does not require loads to independent bytes
to be ordered without adding an explicit barrier.

In ixgbe_clean_rx_irq we load the status bit then load the packet data.
With packet split disabled if these loads go out of order we get a
stale packet, but we will notice the bad sequence numbers and drop it.

The problem occurs with packet split enabled where the TCP/IP header
and data are in different descriptors. If the reads go out of order
we may have data that doesn't match the TCP/IP header. Since we use
hardware checksumming this bad data is never verified and it makes it
all the way to the application.

This bug was found during stress testing and adding this barrier has
been shown to fix it.  The bug can manifest as a data integrity issue
(bad payload data) or as a BUG in skb_pull().

This was a nasty bug to hunt down, if people agree with the fix I think
it's a candidate for stable.

Previously Submitted to e1000-devel only for ixgbe

http://marc.info/?l=e1000-devel&m=126593062701537&w=3

We've now seen this problem hit with other device drivers (e1000e mostly)
So I'm resubmitting with fixes for other Intel Device Drivers with
similar issues.

driver will never see them.  In SR-IOV mode limit the number of tx queues

the PF cannot communciate with the VF and should be considered for 2.6.34

c97ec42a7a igb: add registers etc. printout code just before resetting adapters
This patch adds registers (,tx/rx rings' status and so on) printout
code just before resetting adapters. This will be helpful for detecting
the root cause of adapters reset.

59d7198935 igb: convert igb from using PCI DMA functions to using DMA API functions
This patch makes it so that igb now uses the DMA API functions instead of
the PCI API functions.  To do this the pci_dev pointer that was in the
rings has been replaced with a device pointer, and as a result all
references to [tr]x_ring->pdev have been replaced with [tr]x_ring->dev.

This patch is based of of work originally done by Nicholas Nunley.

This change corrects the fact that we were not reporting Gen2 link speeds
when we were in fact connected at Gen2 rates.

aa913403fe igb: double increment nr_frags
There is no need to increment nr_frags because skb_fill_page_desc increments
it.

1b6e66182d igb: modify register test for i350 to reflect read only bits in RDLEN/TDLEN
The registers for RDLEN/TDLEN on i350 have the first 7 bits as read only.
This is a change from previous hardware in which it was only the first 4
bits that were read only.

22bedad3ce net: convert multicast list to list_head
Converts the list and the core manipulating with it to be the same as uc_list.

+uses two functions for adding/removing mc address (normal and "global"
 variant) instead of a function parameter.
+removes dev_mcast.c completely.
+exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for
 manipulation with lists on a sandbox (used in bonding and 80211 drivers)
