Matthew Vick 1f6e8178d6 igb: Prevent dropped Tx timestamps via work items and interrupts.
In rare circumstances, it's possible a descriptor writeback will occur
before a timestamped Tx packet will go out on the wire, leading to the
driver believing the hardware failed to timestamp the packet. Schedule a
work item for 82576 and use the available time sync interrupt registers
on 82580 and above to account for this.

Matthew Vick a9188028fd igb: Correct PTP support query from ethtool.
Update ethtool_get_ts_info to not report any supported functionality on
82575 and add support for V2 Sync and V2 Delay packets. In the case
where CONFIG_IGB_PTP is not defined, we should be reporting default
values.

v2: Correct the function to return EOPNOTSUPP when there is no PTP support
    or the device does not support PTP. Also fix minor whitespace issue.

Mark Rustad 4ffdf91a5f ixgbe: Improve statistics accuracy for DDP traffic
Noticed that the byte and packet count statistics are under-
counting traffic handled by the DDP offload when there is more
than one DDP completion processed in a single call to
ixgbe_clean_rx_irq. This patch fixes that.

I tried to optimize the setting of the rss value so that it
only would have to be computed once, and only when there is
a DDP completion present.

The PF was not correctly registering any of its VLANs.  As a result any
VLAN tagged traffic from the VF would not be delivered to the PF because
the VLAN was never assigned to the PF pool.

In addition the VF was not allowed to receive traffic from VLAN 0 if it was
allowed to receive untagged frames.  This change corrects that so that it
will correctly receive traffic from VLAN 0.

Yaniv Rosner d3a8f13b11 bnx2x: Link Flap Avoidance
Various flows in the bnx2x driver cause a link-flap - if the link
is up, it would be toggled down (after a mac/phy reset) and then
taken back up.

In many of these cases, there is no need to do cause such a flap,
as the associated flows should not actually affect the link.

This patch adds the 'Link Flap Avoidance' mechanism, which allows
the driver to better determine if a given flow requires a link change,
and thus minimize the number of link flaps caused by the driver.

Santiago Leon d90c92fee8 ibmveth: Fix alignment of rx queue bug
This patch fixes a bug found by Nish Aravamudan
(https://lkml.org/lkml/2012/5/15/220) where the driver is not following
the spec (it is not aligning the rx buffer on a 16-byte boundary) and the
hypervisor aborts the registration, making the device unusable.

The fix follows BenH's recommendation (https://lkml.org/lkml/2012/7/20/461)
to replace the kmalloc+map for a single call to dma_alloc_coherent()
because that function always aligns to a 16-byte boundary.

The stable trees will run into this bug whenever the rx buffer kmalloc call
returns something not aligned on a 16-byte boundary.

Eliezer Tamir ab868256f8 ixgbe: remove old init remnant
Remove a for loop that does nothing in ixgbe_probe().
This is a remnant from when we had IO bars (compare to the ixgb code).

Wu Fengguang b320e97240 i825xx: fix paging fault on znet_probe()
In znet_probe(), strncmp() may access beyond 0x100000 and
trigger the below oops in kvm.  Fix it by limiting the loop
under 0x100000-8. I suspect the limit could be further decreased
to 0x100000-sizeof(struct netidblk), however no datasheet at hand..
